An elementary monodimensional binary cellular automaton -184- with random white starting points -on the bottom line- [Un automate cellulaire binaire monodimensionnel élémentaire -184- avec des points aléatoires de départ blancs -sur la ligne du bas-].
BBB = B
BBW = W
BWB = B
BWW = B
WBB = B
WBW = W
WWB = W
WWW = W
with, for example, "BWW = B" meaning:
if ((CELL(x-1,t)==Black)&&(CELL(x,t)==White)&&(CELL(x+1,t)==White)) then CELL(x,t+1)=BlackThis cellular automaton is called 184. As a matter of fact, when concatenating the right-hand sides of the preceding rules one obtains:
-------- --------
BWBBBWWW = 01000111 = 10111000
and the binary number 10111000 equals the decimal number 184 (for 184=128+32+16+8).
It can be displayed as the following cubes:
