COMMENTS

The sequence prime(prime(i)) for i = 1, 2, 3,... is in A006450. The paper by Bayless et al. discusses these primes.
It is not clear what the "twin primes" are in the sequence prime(prime(prime(i))). I computed 10^7 terms, last of which is 91132598237.  T. D. Noe, Aug 10 2013

EXAMPLE

5 is here because 5 and 11 are adjacent terms in A006450 differing by 6.


MATHEMATICA

nn = 10000; t = Table[Prime[Prime[n]], {n, nn}]; s = Select[Range[nn  1], t[[# + 1]]  t[[#]] == 6 &]; t[[s]]
