COMMENTS

A question related to this sequence: prove the convergence or divergence of the infinite series Sum_{i=1,2,3,....} 1/LookAndSay[i]. (Numerical experiments suggest that this diverges slowly.)

LINKS

Table of n, a(n) for n=1..40.

EXAMPLE

a(2) = LookAndSay(1) + LookAndSay(2) = 11 (one "1") + 12 (one "2") = 23.
