%N a[n]= is the nth smallest product of 3 odd primes m=p1*p2*p3, such that (d+m/d)/2 are all primes for each d dividing m.
%e 165=3.5.11 and (3.5.11+1)/2=83, (3+5.7)/2=19, (5+3.7)/2=13, (7+3.5)/2=11 are all primes and 165 is the 2nd smallest number of such form, so a[2]=165
%Y Cf. A128281, A005383, A128283, A128285, A128286.
