 OFFSET 0,1 LINKS Eric M. Schmidt, Table of n, a(n) for n = 0..1000 Eric M. Schmidt, C++ code to compute this sequence Mirek Wojtowicz, Information on many 2D cellular automata EXAMPLE a(1)= 5 because the L-pentomino contains 5 cells. a(2)= 5 because 5 cells are neighbors (in a Moore neighborhood) of exactly 2 of the original 5 cells. a(3)= 7 because 7 cells are neighbors of exactly 2 of the previous 5 cells.
