Up to 10^14, there are only 9 palindromic prime powers of prime numbers.

Cf. A053810, A075308, subset of A072037.

a = {}; Do[pp = Prime[n]^Prime[i]; d = IntegerDigits[pp]; If[d == Reverse[d], a = Append[a, pp]], {n, 1, PrimePi[ Sqrt[10^21]]}, {i, 1, PrimePi[ Floor[ Log[ Prime[n], 10^21]]]}]; Sort[a]
