Property
Stephen Wolfram made a comment on Rule 90 saying that it will reproduce the first line after some iterations. Now any automata on a finite grid must necessarily repeat itself sooner or later, since there's only limited number of configurations. The same is true for random number generators or the ducci sequences. But only some automata would reproduce any starting configuration, the rest may be caught in loops that do not include that specific configuration. Is this a noteworthy "interesting property" of Rule 90 or some larger class of rules? EverGreg (talk) 19:35, 3 September 2010 (UTC)
 * Uhm wait.. The sierpinski triangle is a counter-example, isn't it? the starting configuration never re-appears. EverGreg (talk) 19:43, 3 September 2010 (UTC)


 * For any finite pattern it eventually produces two copies of that pattern, that's probably what he meant by reproduce. Dmcq (talk) 21:06, 3 September 2010 (UTC)

"Bowtie Pasta" replicator
Where does the name "bowtie pasta" for the HighLife replicator come from? I've never seen it used before. — Preceding unsigned comment added by EZ132 (talk • contribs) 23:58, 25 November 2020 (UTC)
 * That name is used (with the slightly different spelling "bow tie pasta") by . Evans might have invented the name; it doesn't seem to be widespread beyond that publication. —David Eppstein (talk) 00:11, 26 November 2020 (UTC)
