%Y Cf. A036378 (number of primes summed).
%Y Cf. A293696 (triangle of partial sums).
%Y Minimum is A014210 or A104080, indices A372684.
%Y Maximum is A014234, delta A013603.
%Y Counting all numbers (not just prime) gives A049775.
%Y For squarefree instead of prime numbers we have A373123, length A077643.
%Y For prime indices we have A373124.
%Y Partial sums give A130739(n+1).
