%N A007619 Wilson quotients: ((p-1)!+1)/p.
%C A007619 Suggested by the Wilson-Lagrange Theorem: An integer p > 1 is a prime 
               if and only if (p-1)! == -1 (mod p).
%C A007619 Define b(n) = ( (n-1)*(n^2-3*n+1)*b(n-1) - (n-2)^3*b(n-2) )/(n*(n-3)); 
               b(2) = b(3) = 1; sequence gives b(primes).
