Code: Select all

`x = 73, y = 2, rule = B3/S23`

57o$73o!

So this is 8 characters of RLE, including the terminator, that produces a stabilized switch engine (block making variety). Is this known? I tried searching on the RLE in quotes and did not find it.

It is a bit long to enter by hand, but doable. Pretty easy to remember 57 and 73 though. Are there shorter RLE strings that give infinite growth? It would require checking lines of cells up to 999999 in length. Has anyone tried it?

Same encoding length but infinite gliders.

Code: Select all

`x = 73, y = 2, rule = B3/S23`

57o$95o!

Both have a run of 57. I am not sure if there is a reason besides coincidence.
