Comments

None of these partial sums of "bemirps: primes that yield a different prime when turned upside down with reversals of both being two more different primes" is itself prime. So what is the first (nontrivial) prime partial sum of bemirps? Of emirps? Of "norep emirps": primes with distinct digits which remain prime when reversed? Of emirpimes? I suspect that G. L. Honaker, Jr. would be delighted to have any of these.
