%N Primes > 3.
%C Or, prime sums of primes (without repetition).
%C Or, smallest prime > n-th odd prime.
%C Or, primes p such that p*(p+1)/2-1 is a composite.
%C Note that p*(p+1)/2-1 = (1/2)*(p - 1)*(p + 2), also 3*(3+1)/2-1 = 5. - _Joerg Arndt_, Jan 12 2011.
%C The inclusion of this sequence in the OEIS is justified by the fact that a number of other sequences can be more simply described using it, and also so that Superseeker can make use of it. - _N. J. A. Sloane_, Aug 24 2012
%C Also level number where the total number of faces is increased by 4 in the perspective view of the stepped pyramid described in A245092. - _Omar E. Pol_, Mar 20 2019
