BBB = W
BBW = B
BWB = B
BWW = W
WBB = B
WBW = W
WWB = B
WWW = W
with, for example, "BWW = W" meaning:
if ((CELL(x-1,t)==Black)&&(CELL(x,t)==White)&&(CELL(x+1,t)==White)) then CELL(x,t+1)=WhiteThis cellular automaton is called 106. As a matter of fact, when concatenating the right-hand sides of the preceding rules one obtains:
-------- --------
WBBWBWBW = 10010101 = 01101010
and the binary number 01010110 equals the decimal number 106 (for 106=64+32+8+2).
It can be displayed as the following cubes:
