Re: Things You've Been Doing Other Than CGoL
I downloaded this wonderful program called Space Engine. It's interesting (since astronomy/astrophysics in general are interesting), and you can have fun flying spaceships around. Now I just need to learn how to avoid crashing into planets so much. (It turns out "autopilot" is really just "automatic crashing into selected object.")
I wonder if autopilot even attempts to reach the future position of the planet, instead of just going straight towards the object and then having to keep readjusting to keep heading straight towards it.

Re: Things You've Been Doing Other Than CGoL
Been thinking about geometry lately.
Since you can create a great dodecahedron from 12 intersecting pentagons, is there such thing as a "great cube"? This would consist of 6 squares, linked together to form a shape like some sort of excavated octahedron (sharing the same vertex and edge arrangement just like the great dodecahedron does the icosahedron). It probably wouldn't be very regular though since the squares would be directly overlapping each other.

Re: Things You've Been Doing Other Than CGoL
Yes, you can create something like this. It wouldn't be a true polyhedron, though, as the squares would come in three overlapping sets of two. It is a degenerate polyhedron, but it still fulfills the basic rule that two faces meet at an edge. In fact, it is a compound of three square dihedra.muzik wrote:Been thinking about geometry lately.

No, it would be perfectly regular. The cubic symmetry group of transformations allow any face to be mapped onto every other face in 8 ways, equal to the order of symmetry of the faces. There are also four ways to map an edge onto each other edge, and 8 ways to map each vertex of valence 4 (which is actually two coinciding vertices) onto each other vertex. This means that this is a truly regular compound, and in fact the square dihedra can be replaced by cubes (as square prisms) or even octagonal prisms and the resulting figure will still be vertextransitive, if also coincidic.It probably wouldn't be very regular though since the squares would be directly overlapping each other.
Re: Things You've Been Doing Other Than CGoL
and the "great octahedron" would just be the same as the stellated octahedron/compound of two tetrahedra, right?

Re: Things You've Been Doing Other Than CGoL
Another geometry related thought: would the star polygon {4/2} be a compound of two digons, or a square stellated to infinity as in the tetrahemihexacron?

Re: Things You've Been Doing Other Than CGoL
Under common usage, {(n*a)/(n*b)} (where n, a, b are integers, and a and b are coprime) is commonly used to represent a compound of n a/bgons (in this case, n = 2, a = 2, and b = 1, so it is a compound of 2 digons as you said) but a more professional notation, used here uses {(n*a)/(n*b)} to represent a different shape, an {a/b}gon that closes after reaching the starting point n times. To visualize this for {6/2}, imagine drawing a triangle but continuing past the starting point and tracing each edge again before closing. The finished figure has six edges that overlap in three pairs. {4/2} would be a similar thing, a doublywound digon.muzik wrote:Another geometry related thought: would the star polygon {4/2} be a compound of two digons, or a square stellated to infinity as in the tetrahemihexacron?
So to answer your question, {4/2} technically represents neither of the things you said, but it could be used to represent the compound of two digons under a casual interpretation. Many of your questions seem to relate to how naming systems (describing similarities between shapes) should get extended to cover unconventional cases which, while a fun exercise, usually produces the best results when you open your mind to the exact algorithm the naming system uses and apply it in the most literal way possible. Sometimes there is more than one way to do this; I prefer the notation I described as "technical" because it considers the shape topologically and only makes the edges the same length as an afterthought.
About the infinite stellation, I'm not as partial to this one because it requires the definition of vertices at infinity. I'm rather uncomfortable with the duals of hemipolyhedra for the same reason. I still never really tried to visualize the tetrahemihexacron, mostly because the 6 infinite extensions that only describe 3 vertices confuse me.
Re: Things You've Been Doing Other Than CGoL
Well, my two thoughts were these:
 The 2 in 4/2 means joining every second point in the outside to each other, without leaving out any points, giving the plus shape, and
 the 2 meaning the first stellation (since 1 means the convex polygon, so subtracting 1 from the 2 gives the first stellation), and since the two edges are parallel they would never meet and simply give an infinite figure.
So, more random shenanigans:
 Are there any polyhedra that are isogonal, isohedral and isotoxal, but the faces aren't all strictly regular polygons? I'm thinking the stellations of the icosahedron might count as these.
 Assuming that the figure {6/3} represents a star figure compound of three digons and not just a triplywound digon, would this mean that the figure {3/1.5} would somehow be half of this? To me it would seem like a "perfect Y", with three equally spaced lines radiating out from a point, similarly to one of those fidget spinners, or the shape you can draw inside a hexagon to make it look like an opaque cube.

Re: Things You've Been Doing Other Than CGoL
Something that's always irritated me is music notated in 3/8 time. It's really just 3/4, 6/8, 9/8, 12/8, or maybe a mixed combination of the previous ones.
6/4 divided up into 2 groups of 3 beats always used to irritate me a similar reason; it's normally just 2 3/4 bars ungainly smashed together; until I heard a piece where it wasn't just misnotated 3/4. By the way, 6/4 divided up the other way is one of my favorite time signatures, along with 11/8 and anything with a multiple of 5 in the numerator.

I've tried experimenting with 11/4, 13/4, 17/4 and 19/4 recently. Nice set of quadruplet primes.

Re: Things You've Been Doing Other Than CGoL
I've been working on a large number notation comparable to Bowers' exploding array function and faster than ExtensibleE notation, I believe. You just have to look it up. On the subject, Calcyman, you made the xi function right?

Re: Things You've Been Doing Other Than CGoL
I see what you mean. The rational part of my mind knew it had to happen eventually, but I still knew how excited I would be when it happened because I always thought of Bowers as a person whose work was underappreciated.AforAmpere wrote:I'm kind of surprised that I'm the first
I figured out about Bowers Exploding Array function in 2011, after I discovered his work with polytopes and then explored the rest of his site. I figured out how the arrays worked all the way up to early tetrational arrays, and then gave up trying to visualize them but trusted that Bowers had provided a foolproof way to turn any unsolved array into a space that could be filled with numbers to create another array; with that in mind I was able to understand legion arrays too, as they involve the repeated application of the "array of" function, which takes an unsolved array and turns it into another array to be filled with the same number. However, recently on Googology Wiki there has been talk on a way to "formalize" the arrayof notation so there was a welldefined method of describing the space of an array by another array. Mostly this involves extending the definition of Bowers Exploding Array Function so that the arguments can be ordinals as well. The last time I checked, they hadn't gotten very far.
By the way, Calcyman's Xi function is completely different. It grows uncomputably fast, which means that it grows faster than all functions whose values can be computed by a theoretical computer with infinite memory and time. This means that Xi(n) will eventually become larger than any function made by taking a Bowers array and setting some entries to n. (Assuming, of course, that all array spaces really can be defined.)
