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. [From Nathaniel Johnston (nathaniel(AT)nathanieljohnston.com), Jun 08 2009]
