%N Indices of primes in A133547, i.e., numbers n such that the sum of the squares of the first n odd primes is prime.
%C All terms are necessarily odd. Thus one could also consider the sequence floor(a(n)/2) = (1,2,4,5,11,14,31,32,35,...). Other possible variations would be to list the index a(n)+1 of the largest prime in that sum, or, since this is always even, (a(n)+1)/2 = (2,3,5,6,12,15,32,33,36,...).
%F A160359(n) = A133547(a(n)) = A024450(a(n)+1)  4.
