%N A079664 a(n) = Sum_{i=1..n} LookAndSay(i).
%C A079664 A question related to this sequence: prove the convergence or divergence of the infinite series Sum_{i>=1} 1/LookAndSay(i). (Numerical experiments suggest that this diverges slowly.)
%e A079664 a(2) = LookAndSay(1) + LookAndSay(2) = 11 (one "1") + 12 (one "2") = 23.
%Y A079664 Partial sums of A047842, n>=1.
