%N Lexicographically earliest sequence of distinct primes in which the concatenation of any number of consecutive terms is composite.
%C This sequence is very likely a permutation of the primes.

%e Start with 2. The second term cannot be 3 because the concatenation of 2 and 3 is prime. However, 5 works. The third term cannot be 3 because the concatenation of 5 and 3 is prime. It cannot be 7 because the concatenation of 2 and 5 and 7 is prime. However, 11 works.
