#Life 1.05 #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 growth 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 #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. #D This spacefiller by David Bell, September 1993. #N #P -14 -21 .....*.* ....*..* ...** ..* .**** *....* *..* *..* .*.........***...*** ..****.*..*..*...*..* ...*...*.....*...* ....*........*...* ....*.*......*...* . ...***.....***...*** ...**.......*.....* ...***......******* ...........*.......* ....*.*...*********** ...*..*..*............** ...*.....************...* ...*...*.............*...* ....*...************.....* .....**............*..*..* ........***********...*.* .........*.......* ..........*******......*** ..........*.....*.......** .........***...***.....*** . ...........*...*......*.* ...........*...*........* ...........*...*.....*...* ........*..*...*..*..*.**** .........***...***.........* .........................*..* .........................*..* .......................*....* ........................**** ..........................* ........................** .....................*..* .....................*.*
