%C Is this a duplicate of A163678? [From _R. J. Mathar_, Jul 22 2010]

%e Smallest entries of all three kinds:

%e a(1) = 1913 because prime(293)=1913 and prime(294)=1931 are anagrams

%e a(2) = 18379 because prime(2106)=18379 and prime(2107)= 18397 are anagrams

%e a(13) = 48091 because prime(4953)=48091 and prime(4954)= 48109 are anagrams.

%Y A069567 Smaller members of Ormiston prime pairs.
