For me the Name is clear and a glance at the data is enough to confirm the intended meaning. The part “..of prime numbers” of the definition is not redundant since if it were removed we would have just “Prime powers”, meaning that primes are being raised to powers but without being clear about what those powers (exponents) actually are (Without restriction on the exponents we get
A000961). A053810 restricts the exponents to primes.
If a name change is required consider “Numbers p^k, where both p and k are prime.”
Best regards
David Sycamore.
