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)
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)
Making the 3-glider database less misleading
I have made some minor modifications to the page to make the 3-glider database slightly less misleading, and to include the possibility of duplicate syntheses within it. However, I could not obtain a good definition of "duplicate syntheses". Therefore, if you find a good definition of this, or if you have a better way to express these ideas, please edit the page directly.
