Comments

Bemirps: primes that yield a different prime when turned upside down with reversals of both being two more different primes (see A048895).

Examples

			111696081881 and 111696081883 twin primes,
111969081881 and 111969081883 twin primes,
188180696111 and 188180696113 twin primes,
188180969111 and 188180969113 twin primes,
so the least bemirp 111696081881 = a(12).
