%S A077022 1,6,17,11156,16548
%N A077022 Values of n such that sum of first n primes squared is divisible by n-th 
               prime.
%C A077022 Remainder, a(n), when sum of first n primes squared is divided by n-th 
               prime in A072004. In A072004, in three cases, a(n)=0 that is the 
               sum of squares of first n primes is divisible by n-th prime. Here 
               we added two more cases when a(n)=0.
%e A077022 6 is OK because (p(1)^2+...+p(6)^2)/p(6)=29; 17 is OK because (p(1)^2+...+p(17)^2)/
               p(17)=284; 11156 is OK because (p(1)^2+...+p(11156)^2)/p(11156)=410066261; 
               16548 is OK because (p(1)^2+...+p(16548 )^2)/p(16548)=941945317.
