COMMENTS
| Primes with digits already in ascending order (like 13 and 2357) are trivial cases and are therefore excluded.
|
|
|
EXAMPLE
| a(1)=31 because an ascending sort of 31's digits yields 13 which is also prime. a(100)=3527 because an ascending sort of 3527's digits yields 2357 which is also prime.
