A068652 is the sequence of rotational primes. It references A003459, the sequence of absolute primes, the numbers of which all the permutations are primes. That sequence contains the numbers 1111111111111111111, and 11111111111111111111111. There's also a link to this page: MATHEWS: Circular, Permutable, Truncatable and Deletable Primes, which lists all known rotational primes. According to that list, you probably won't find any more rotational primes.
