Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

Table of n, a(n) for n=1..16.

EXAMPLE

Rule: B345/S4567

For n=4, a 8 by 8 square of ON cells stabilizes in 2 generations, becoming a period 6 oscillator, so a(4)=6.

For n=10, a 20 by 20 square of ON cells eventually stabilizes as a period 416 oscillator, so a(10)=416.
