A nice reduction to the second oscillator above:

x = 20, y = 9, rule = B3/S23

Floor 27 contains nothing. The rooms are completely empty. There aren't even any rooms, actually, because that would require walls, and there's nothing on this floor. No ceiling. (the rest of the building continues upward approximately 100 meters off to the side) No floor, somehow: We're still debat...

This could be a possible starting point for 6xn block arrays if not for the fact that these two gliders intersect paths: x = 15, y = 23, rule = LifeHistory 12.A$4.2A6.A.A$4.A.A5.2A$5.A.A$6.A.A$.2E4.A.A$E.E5.A.A$2.E6.A.A$10.A.

It would help if I knew which of those was the input and which was the subscript, but: You'd probably want to do something like, say, creating an iteration function thus: It(x,y,n+1) = It(f_y(x),y,n); It(x,y,0) = x And then construct the successor fgh as f_(y+1)(x) = It(x,y,x) Piggybacking: def FGH...

and some unrelated block factory/glider gun & obstruction, which works in 2 directions!
Code: Select all
x = 148, y = 69, rule = LifeHistory
block-laying circuit that blocks transparent lanes in two directions

Sadly, passing a signal while the block is present causes an explosion.

If I made a DetLife variant that automatically detected forced supports, would anyone use it?

The first one can be made slightly smaller:
Code: Select all
x = 8, y = 7, rule = LifeHistory
6.2A$2A.2C2.A$A3.C.A$.A.C2.2A$2A.C.A$A2.C.A$2.2C.2A!
The other two are almost certainly minimal.

And the next question is, how to elaborate the casings and yield the version in DRH-oscillators.rle ? I've checked the enormous components_v4.rle; it says that the bi-block can be converted into a boat on block, which can lead to a table on block, a long-bookend on block, or a cap on block (all the...

I suspect that further developments will unfold if a 4g equivalent to the upper activation of the loaf-bend-tail area is found, Such that it doesn't plume out so far towards the sufficiently-long boat fuses. If we can get more clearance there, my suggestion from the Discord that we insert two domin...

Final step for 56P6H1V0! Over on the Discord, Kazyan found the key step of "activating" the pythons and with a bit of help with the cleanup from others I was able to put together this final step: rle The base still-life is pretty huge but I suspect its synthesis should be fairly easy in comparison ...

R2D2 in 86 gliders (If I counted correctly): ... Very nice! Cleanup in key step can be reduced by two: rle That long canoe looked unnecessary, and it is: x = 51, y = 51, rule = B3/S23 2bo$obo$b2o7$19bo$20b2o$19b2o3$15bobo$16b2o$16bo5bo$23b2o17bo$22b2o16b 2o$41b2o$15bobo$16b2o$16bo4$31b2o$31bobo$33b...

Challenge: come up with a sequence like Gijswijt's sequence with
1) an even harder name to spell and pronounce
2) a slower growth rate

Just give the inverse Ackermann sequence some silly name.

It looks like a "model" is essentially a set large enough that logical axioms and formulae can be interpreted and manipulated as subsets of said set.
Someone better-trained in set theory than myself will have to refine that.

The base of natural logarithm e has many characteristics/defnitions, e.g. e₁=lim(x→∞)(1+1/x)^x e₂=∑(n=0 to ∞)(1/n!) e₃ is the unique solution x for ∫(t=1 to x)(1/t)dt = 1 e₄ is the unique number a such that f(x)=a^x is equal to its own derivative and has unit tangent slope at (0,f(0)) How to prove ...

But can anyone give me a simple understanding of Mahlos like this?

BlinkerSpawn

(vote) Not entirely sure, but this one might also be invalid since the numbers need to have two digits (i.e. #01 instead of #1) I get the need for consistency, but unless you have some sort of script that's pulling the contents of these posts and tallying I don't see what difference it would make.

So instead I'll work on a way to turn trees into ordinals... This notation, given I'm interpreting it correctly, has limit e_0. Proof: From the successorship and expansion rules we get that a-b must have value a+b. The tree (a+1)-0 is equivalent to a-a-a-a-... with w a's, so the value of (a+1)-0 is...
