%N a[n]= is the nth smallest product of 4 odd primes m=p1*p2*p3*p4, such that (d+m/d)/2 are all primes for each d dividing m.
%e 1365=3.5.7.13 and (3.5.7.13+1)/2, (3+5.7.13)/2, (5+3.7.13)/2, (7+3.5.13)/2,
%e (13+3.5.7)/2, (3.5+7.13)/2, (3.7+5.13)/2, (3.13+5.7)/2 are all primes and 1365 is the smallest such integer which is the product of 4 primes, so a[1]=1365
