Perhaps the n-th term begins with the concatenation of the first (n-1) 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 n-th term starts with the concatenation of the first (n-2) primes. - M. F. Hasler, Mar 20 2011
