#C [[ GRID THEME BOOK ]]
A glider collision that produces a block, but is not considered a
valid glider synthesis since two of the gliders cannot get into
position without crossing paths in the first place.
x = 10, y = 7, rule = B3/S23

#C [[ GRID THEME BOOK ]]
A collection of all 71 distinct two-glider collisions, grouped by
what they synthesize. Compiled on January 29, 2005 by Jason Summers.
