Converts one glider into 4 for any input stream
with a period of 672 or greater, unless pipelining
techniques are employed. It is a great challenge
to come up with the small, fast reflector that
consists solely of still-lifes. Dieter Leithner
(dietrich.deithner@dlr.de) is offering a $100
prize for the first stable glider reflector that
fits within a 50x50 box.
A glider collides with a boat in generation 97,
destroying the boat but creating a B-heptomino at
generation 107. This is converted into a Herschel
in 59 generations. Herschel conduits of lengths 64,
77, 77, 64, 64, 77, 119, and 64 set the Herschel up
for a final collision to recreate the destroyed
boat.
The first stable glider reflectors were created by
Paul Callahan and Dean Hickerson in late 1996. This
one by Dave Buckingham, May 30, 1997.
