	OFFSET	`1,1`
	COMMENT	`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.`
	CROSSREFS	`Cf. A003459, A086402.` `Sequence in context: A142110 A110831 A086042 this_sequence A109309 A127191 A003542` `Adjacent sequences: A086048 A086049 A086050 this_sequence A086052 A086053 A086054`
