%N A086051 Nontrivial numbers which are prime, contain no zero digits and yield 
               another prime when their digits are sorted in ascending order.
%C A086051 Primes with digits already in ascending order (like 13 and 2357) are 
               trivial cases and are therefore excluded.
%e A086051 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.
%Y A086051 Cf. A003459, A086402.
