Re: Thread for your unsure discoveries

6x6 patterns in an unbounded universe don't reduce the number of cases nearly as much as 6x6 patterns on a torus, but we can still knock off a factor of 8 ... ish ... from the 2^36 = 68.7 billion case count. When I think about it more carefully, it might be too early to do 6x6 before 3x3, 4x4 and 5...

Re: Thread for your unsure discoveries

The second one is the longest lasting 6x6 diehard I have seen so far. It lasts 254 ticks. x = 6, y = 6, rule = B3/S23 b2o$2o$o$bo2b2o$b4o$2b2o! That looks like it ought to have a 6x6 predecessor, but it doesn't -- I tried the same bounding box in JLS, and also 6x6 boxes offset by one cell orthogona...

Re: Thread for your unsure discoveries

Here are two more diehards I thought might be worth sharing. The first one has just 15 cells and lasts 1068 ticks. I encountered it in two different soups. x = 19, y = 7, rule = B3/S23 13bo3bo$13b3o2bo$bo15b2o$obo$bo$9b2o$9bo! The second one is the longest lasting 6x6 diehard I have seen so far. It ...

Re: Thread for basic questions

Does anyone know if there is a database or a collection for small diehards available online? By 'small' I mean patterns with initial population at most 20 or so and a bounding box at most 10x10 or so. Preferably with long lifespans. I have been trying to find patterns like these from Catagolue soups...

Re: Thread for your unsure discoveries

Here is an 8x9 diehard that lasts 889 generations. x = 9, y = 8, rule = B3/S23 bob4o$bo2bobobo$8bo$o$o$o3bo$4bo$4b3o! This version has 18 cells, but there is a 9x9 variant with 17 cells. This is the first pattern I have posted, and I might not have done it correctly, my apologies. I found it from a ...

Re: Thread for basic questions

Hi, I'm pretty new here and would like to know what is the easiest way of investigating soups from Catagolue's database with just a smartphone. Specifically I'm interested in "messless methuselahs" or diehard soups. My plan is to look through a bunch of them and hopefully find some small, long livin...

Re: Introductions

Hi, I'm new here but I have been a fan of cellular automata for a long time. I have studied many kinds of rules in a hexagonal grid using a self-written program. None of them were quite as interesting or versatile as the Game of Life but some came close. I might share some of the stuff I found at so...
