A179413

The number of columns with alive cells in the n-th generation of cyclic sequence of patterns given in A179412, played in Conway's Game of Life on the 8x8 toroidal grid.

3, 4, 5, 5, 6, 6, 6, 7, 8, 8, 8, 8, 7, 8, 8, 8, 8, 8, 7, 7, 8, 8, 8, 7, 7, 6, 3, 5, 5, 5, 6, 8, 7, 8, 8, 7, 7, 7, 8, 7, 8, 8, 8, 7, 7, 8, 8, 8, 6, 6, 7, 5, 6, 8, 7, 7, 8, 8, 8, 6, 7, 7, 8, 6, 6, 4, 3, 4, 5, 5, 6, 6, 6, 7, 8, 8, 8, 8, 7, 8, 8, 8, 8, 8, 7, 7, 8, 8, 8, 7, 7, 6, 3, 5, 5, 5, 6, 8, 7

COMMENTS

Period 66. The sequence begins (from offset 0) with its lexicographically earliest rotation.

The mean value of terms in the whole period of 66 is 6.84848.

EXAMPLE

See illustrations in A179412. In the first four patterns there are alive cells in 3, 4, 5, 5 and 5 columns, thus a(0)=3, a(1)=4, and a(2)=a(3)=5.
