Re: Golly's rule bug?

As of now, Golly RuleLoader does not support 0,0,0,0,0,0,0,0,0,1 "correctly"; it makes exponentially expanding blocks when, mathematically speaking, all cells out to infinity should be turned on. This shouldn't be much of an issue though, because of the following fix. If you want a rule that turns o...

Re: (27,1)c/72 caterpillar challenge

Could there be something that deflects the gliders back around to the front again? No. 27/72 is greater than 1/4. How is that even possible. Like, doesn't that mean ships can travel faster than c/4 diagonally or something What codeholic means is that the orthogonal speed of this theoretical (27,1)c...

Re: 24a/256c (Hex Life) a.k.a 2om4o/2o3m56

It's a puffer and a rake at the same time... I'm a bit lost on the terminology here. At least when applied to Life, a rake is a puffer that emits only spaceships. Also, I think the B and S are swapped in your rule name. But that's my fault for writing Survive/Birth first when most of the forum does...

Re: Rule request thread

Can someone make a rule in which spaceships travelling faster than light speed exist? I'm pretty sure that's not possible in the current moore neighbor hood, but you can make FTL expanding cubes by putting 0,0,0,0,0,0,0,0,0,1 into your rule file Golly doesn't handle 0,0,0,0,0,0,0,0,0,1 properly (i....

Re: having this error with gfind

Try the following:

There will be some warnings (which without -fpermissive would be errors) but I don't think there's any way to get rid of them.

Actually, if you look in Volume 1, Conway refers to gliders as "featherweight spaceships". Language evolves over time.

That D-shaped thing is commonly known as a cap.

Thus the still life is known as "cap and table" (Catagolue) or "up table on cap" (from http://codercontest.com/mniemiec/lifesrch.htm).
