COMMENTS

Perhaps the nth term begins with the concatenation of the first (n1) primes, except for n = 3.
The 9th, 11th, 12th, 13th, .... terms are other counterexamples to the above "conjecture". On the other hand, it seems almost sure that the nth term starts with the concatenation of the first (n2) primes.  M. F. Hasler, Mar 20 2011
