%N Decimal representation of the n-th iteration of the Conway’s game of life starting with four adjacent rows of lines turned on to positive and negative infinity.

%C It is conjectured that every term has a prime factor that does not divide any previous term.

%e 0th iteration = 1111 = 15, 1st iteration = 100001 = 33, 2nd iteration = 11100111 = 231, 3rd iteration = 1000110001 = 561, 4th iteration = 111010010111 = 3735, 5th iteration = 10000111100001 = 8673, ... .
