I first discussed this in an earlier thread on the Other Cellular Automata forums, and the thread contains some interesting patterns from other users. There is also an old thread discussing this rule, and the rule is on Catalogue.
Futzing around with the rule, I found a 14c/28 puffer.
Code: Select all
x = 24, y = 14, rule = 23/3/3

Two, because rakes of longer periods may be useful in the construction of a breeder, c/2 spaceships of other periods would be useful when their periods are combined with the 14c/28 puffer, and I would like to ask the best way to search for spaceships of unusual periods.
Three, in the case that I do find a sufficiently small/long-period rake, I would then need to find a spaceship synthesis for a small infinite growth pattern, the best candidate for which I believe to be the 14c/28 puffer itself, although other puffers have been found, like this one by Schiaparelliorbust and RocknLol:

These questions are specific to the rule 23/3/3 but I have been told that it wouldn't be out of the question to believe that any approach for solving these problems algorithmically doesn't have a wider application.
Thank you.
