COMMENTS

For n = 56, the pattern produces gliders and thus does not oscillate in the truest sense of the word. For n = 57, no gliders are produced and a(57) = 2. There exists an N such that for all n >= N, the row of n alive cells produces gliders and thus does not oscillate. [Nathaniel Johnston, Jun 08 2009]

EXAMPLE

a(10) = 15 because a line of 10 cells becomes the pentadecathlon.
a(56) = 2 because a line of 56 cells becomes 4 gliders (which we ignore) and a remaining pattern of period 2.  Eric M. Schmidt, May 24 2014
