%N Partial sums of A102659 read as decimal integers.
%C The initial 5 ones of 11111843 of a(32) leads me to conjecture that some element of this sequence is, base 10, a concatenation of the digits (1,2). Could there be an element which is also one of the Lyndon words in the underlying A102659?
%C The subsequence of primes in this partial sum begins: 3, 127, 1361, 25939, 183829, 2208497, 3319619. [From _Jonathan Vos Post_, Mar 21 2010]
%e a(25) = 1 + 2 + 12 + 112 + 122 + 1112 + 1122 + 1222 + 11112 + 11122 + 11212 + 11222 + 12122 + 12222 + 111112 + 111122 + 111212 + 111222 + 112122 + 112212 + 112222 + 121222 + 122222 + 1111112 + 1111122 = 3319619 is prime. [From _Jonathan Vos Post_, Mar 21 2010]
