All terms == 5 mod 6. - Zak Seidov, Jan 01 2013

There are no two consecutive primes in the sequence, while there are such primes p=prime(m) that q=prime(m+2) is also a term.

First such p's are at indices 554, 908, 1902, 2588, 3035, 5320, 6213, 6881, 7853, 8262, which correspond to 10237391, 15442121, 27374771, 36040469, 41216027, 66544301, 76313597, 83565611, 93112589, 97515359 (respectively). Note that a(554) = 10237391 = A226657(31). - Zak Seidov, Jul 01 2015
