COMMENTS

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.

LINKS

Table of n, a(n) for n=1..13.

FORMULA

a(n) = A000040(n)^A002808(n).

EXAMPLE

a(3)=5^8=390625 because 5 is the 3rd prime number and 8 is the 3rd composite number.

MATHEMATICA

p2c[n_]:=Module[{prs=Prime[Range[n]], cmps}, cmps=Take[Complement[Range[4, Last[prs]], prs], n]; First[#]^Last[#]&/@Thread[{prs, cmps}]]; p2c[20] (* Harvey P. Dale, Jan 20 2012 *)
