%C A245274 See comment in A243937.
%C A245274 If prime p is not in A062326, then p^2 is in the sequence.
%C A245274 If p>3 and p,p+2 are twin primes, then p*(p+2) is in the sequence. Indeed, it can be shown that in this case (p+1)^2 is in A243937. lpf((p+1)^2-1)=p while lpf((p+1)^2-3)=3, since for lesser p>3 of twin prime p+1==0(mod 6).
