Same as primes in A213356.

Same as primes < 96 that are not the sum of distinct primes 3, 5, 11, 17, 31, 41, 59, 67, 83 (= terms of A006450 < 96), because Dressler and Parker prove that every integer > 96 is a sum of distinct terms of A006450 (primes with prime subscripts).

R. E. Dressler and S. T. Parker, Primes with a prime subscript, J. ACM 22 (1975) 380-381.

Example

Prime(Prime(1)) = Prime(2) = 3 and Prime(Prime(2)) = Prime(3) = 5 and Prime(Prime(3)) = Prime(5) = 11, so 2 and 7 are members.
