EXAMPLE
|
16 is a term because it is the result of sorting the digits of prime 61 in ascending order, and 61 contains no zeros.
49 is not a term since neither 49 nor 94 are prime, and the prime 409 contains a zero.
133 is a term because while 133 itself is composite, both 313 and 331 are prime and contain no zeros. (End)
