Example

113 is a member as the next to next prime 131 uses the same digits.

Mathematica

p = {0}; q = {1}; r = {1}; Do[ If[p == r, Print[ Prime[n - 3]]]; p = q; q = r; r = Sort[ IntegerDigits[ Prime[n]]], {n, 3 10^3}]
sdQ[n_]:=Sort[IntegerDigits[n]]==Sort[IntegerDigits[NextPrime[n, 2]]]; Select[Prime[Range[4000]], sdQ] (* Harvey P. Dale, Apr 26 2015 *)
