### Game of Life "Glider" chess problems

Continuation from: http://matplus.net/start.php?px=1587108063&app=forum&act=posts&fid=gen&tid=264&pid=18974#n18974

Discussion thread for chess problems with the "Glider" pattern.
https://en.wikipedia.org/w/index.php?title=Glider_(Conway%27s_Life)&oldid=946864418

Patterns:

XXX
--X
-X-

X-X
-XX
-X-

(on a 3x3 board: b1, c2, a3, b3, c3 would be occupied, or b1, b2, c2, a3, c3 would be occupied - rotations are possible but only in multiples of 90 degrees).

(= 10+10 )

Examples for "glider" patterns. Pattern 1 white, pattern 2 black. Vertical/horizontal mirroring and 90, 180, 270 degree rotations are possible.

The "glider" was invented by Richard K. Guy (1917-2020) for John Conway's (1937-2020) "Game of Life". The rules of the Game of Life don't matter here - they can be read at the link below -, but the "glider" is a self-sustaining pattern that "moves" on the grid of the game, in some cases it can transmit information.

I currently try to organize a small contest for original problems with the "glider" pattern. So please don't "use up" all of them yet. :-)
(EDIT: I found a judge also, so I just need a positive reply from officials, and I can start it!)
