%N a(0)=2; for n>0, a(n) = smallest prime not occurring earlier in the sequence such that a(n1)+a(n) is a multiple of n^2. If no such prime exists, the sequence terminates.
%C Is this sequence infinite and, if so, is it a permutation of the primes? The answers are probably Yes and No (7 has not appeared after 10000 terms). Compare A134204.
