'a negative result is still a result'
One of the easiest (lol not really) ways to become famous in the Game of Life is to have the 'gfind' program (found here) running somewhere in the background searching for new spaceship velocities like c/7, 3c/8 etc. But no one actually wants to repeat the searches others have already accomplished, so some sort of collection of such negative results is definitely needed.
For example, I remember a letter by Paul Tooke saying:
(this corresponds toAt 3c/7 I completed asymmetric up to width 11, glide symmetric up to widths
11&12, bilaterally symmetric up to widths 22 (even), 23 (odd) and 25 (odd
with a central 'gutter' of OFF cells).
...
At 3c/8 and 4c/9 I completed the three bilaterally symmetric modes up to
widths 17, 18 & 19.
Code: Select all
gfind b3s23/o7n3agv/l154
Code: Select all
gfind b3s23/o7n3uw/l168
But it was a long time ago;
What is the current status of these searches?
