%N A 2n X 2n square filled with "ON" cells becomes a period a(n) oscillator using the life-like cellular automaton B345/S4567.
%e Rule: B345/S4567
%e For n=4, an 8 X 8 square of ON cells stabilizes in 2 generations, becoming a period 6 oscillator, so a(4)=6.
%e For n=10, a 20 X 20 square of ON cells eventually stabilizes as a period 416 oscillator, so a(10)=416.
