Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N n-th prime number raised to the n-th composite number.
%C This sequence arises as a result of exponentiation with the terms of the sequence A000040 used as the base and the terms of the sequence A002808 used as the exponent.
%F a(n) = A000040(n)^A002808(n).
%e a(3)=5^8=390625 because 5 is the 3rd prime number and 8 is the 3rd composite number.
