#D MAX, the smallest known example of a "spacefiller"
|
|
#D
|
|
#D This is the fastest-growing known pattern in Conway's Game of Life
|
|
#D (possibly the fastest possible). It fills space to a density of 1/2,
|
|
#D conjectured to be the maximum density, and does it at a speed of c/2
|
|
#D in each of the 4 directions, which has been proven to be the maximum
|
|
#D possible speed.
|
|
#D
|
|
#D Population is [(t+19)^2+463]/4 for t divisible by 4;
|
|
#D . [(t+19)^2+487]/4 for t even, not div. by 4;
|
|
#D . [(t+18)^2+639]/4 for t odd.

#D Original construction, top/bottom stretchers by Hartmut Holzwart;

#D Size optimization, left/right stretchers by David Bell;
|
|
#D Original idea, middle part, l/r stretcher connection by Al Hensel.
