Talk:3-glider collision

Isn't there as infinite number of 3-glider collisions? You could use two of the gliders to generate a B-heptomino, which in turn creates two gliders, and then you could put the third glider to collide with one of these two gliders from arbitrarliy far away?

Not necessarily a B-heptomino, a kickbacked glider or a TL+glider or even the 2-glider mess would do so. That idea is not new, as Dave Greene mentioned in this post. The collisions registered into the database are those small and probably useful ones. GUYTU6J (talk) 10:57, 19 May 2020 (UTC)

But then it's impossible to "exhausively" explore all 3-glider collisions. Ultimium (talk) 14:20, 19 May 2020 (UTC)

464745

Carson Cheng edited the page today and a sentence states as follows:

...Under this standard, there are exactly 464,745 “interesting” 3-glider collisions, which are completely enumerated on a 3-glider database...

This is very misleading. Everyone who have worked with the 3g database in glider synthesis will notice its significant number of duplicates among 464745 collisions, and I cannot see a substantiated proof that the enumeration of "interesting" results is complete. (Dvgrn used "fairly", which is not guarantee.) GUYTU6J (talk) 14:04, 23 July 2022 (UTC)

• Can you define what is "duplicate"? Confocal (talk) 14:19, 23 July 2022 (UTC)
