Find the next one.
131 is also a permutable prime.
EDIT
Most likely, in base ten the only permutable primes are
2, 3, 5, 7, 13, 17, 37, 79, 113, 199, 337, their permutations...
2, 3, 5, 7, 13, 17, 37, 79, 113, 199, 337, their permutations...
and 11 again!
ReplyDeletehyper-permutable prime! All the combinations and permutations (with 1 or 2 or 3 figures) are prime! or not?
