COMMENTS
The sequence is obtained continuously by applying the look-and-say rule from seed 3 : 3 -> 1,3 -> 1,1,1,3 -> etc. The sequence is then determined by pairs of digits. Terms of even ranks are counts while odd ranks are figures. A225224 and A221646 are from seed 1 and A088203 from seed 2. [Jean-Christophe Hervé, May 07 2013]
