a(n) = n^n², or (nⁿ)ⁿ. A2489

Self-inverse permutation of natural numbers: a(1)=1, a(p_i) = 2ⁱ, and if n = p_i1 * p_i2 * p_i3 * ... * p_ik-1 * p_ik, where p's are primes, with their indexes are sorted into nondescending order: i1 <= i2 <= i3 <= ... <= i_k-1 <= ik, then a(n) = 2^i1-1 * 3^i2-i1 * 5^i3-i2 * ... * p_k^1+(ik-i_k-1).
