%N The number of rows with alive cells in the n-th generation of cyclic sequence of patterns given in A179409, played in Conway's Game of Life on the 8x8 toroidal grid.
%C The mean value of terms in the whole period of 24 is 6.41667.
%H A. Karttunen, <a href="/A179409/a179409.ijs.txt">J-program for computing the terms of this sequence</a>
%e See illustrations in A179409. In the first four patterns there are alive cells in 4, 2, 4 and 4 rows, thus a(0)=4, a(1)=2 and a(2)=a(3)=4.
