%N Multiplicative function from integers to sums of two squares.
%C The values here are a rearrangement of A001481. The numbers in A001481 have unique factorization (with factors restricted to A001481), with the numbers in A055025 being the "primes".
%F Totally multiplicative with a(Prime(k)) = A055025(k).
%Y Cf. A001481, A055025, A000040.
