%N Primes in A024528.
%C Primes which are the sum of the numerator and the denominator of partial sums of the reciprocals of primes.
%C Each term of this sequence can be expressed as the sum of an expression with exactly one odd term and n even terms, where the odd term is A002110(n)/A002110(1), and n > 0 (see Alexander Adamchuk comment in A024528).
%C a(2) = 11 = 3 + 2 + 6 contains the only prime odd term 3.
%e 3 is a term because 1/2 = 1/2 and 1 + 2 = 3 which is prime.
%e 11 is a term because 1/2 + 1/3 = 5/6 and 5 + 6 = 11 which is prime.
%e 61 is a term because 5/6 + 1/5 = 31/30 and 31 + 30 = 61 which is prime.
%e 457 is a term because 31/30 + 1/7 = 247/210 and 247 + 210 = 457 which is prime.
%Y Intersection of A000040 and A024528.
%Y Cf. A002110.
