%N Lower twin prime-indexed primes in the sequence of prime(prime(i)).
%C The sequence prime(prime(i)) for i = 1, 2, 3,... is in A006450. The paper by Bayless et al. discusses these primes.
%C 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
