## permutable primeAlso known as an absolute prime, a prime
number with at least two distinct digits which remains prime on every
rearrangement (permutation) of the digits. For example, 337 is a permutable
prime because each of 337, 373, and 733 are prime. Most likely, in base
ten, the only permutable primes are 13, 17, 37, 79, 113, 199, 337, and their
permutations. Obviously permutable primes cannot have any of the digits
2, 4, 6, 8 or 5. They also cannot have all four of the digits 1, 3, 7, and
9 simultaneously. ## Related categories• PRIME NUMBERS• TYPES OF NUMBER | |||||
