[seqfan] Re: Look and say -- my parity

[Eric Angelini]

Jean-Marc Falcoz has computed
the longest possible seq starting with 22:

> 27 termes, avec {22, 42, 62, 82, 10231, 11271, 101142, 151152, 181182, 211212, 221262, 251292, 291312, 321342, 352371, 372411, 392451, 442461, 472491, 502521, 512571, 532611, 552651, 602661, 632691, 652731, 672771}

... a longer seq might exist with a
different a(1) -- say 1231. Who knows...
Best,
É.
