s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n+1-k), where k = [ (n+1)/2 ], s = A000201 (lower Wythoff sequence), t = A001950 (upper Wythoff sequence). A24686
Let Dedekind's ψ(m) = product of (p+1)pe-1 for primes p, where pe is a factor of m. Iterating ψ(m) eventually results in a number of form 2a*3b. a(n) is the smallest number that requires n steps to reach such a number. A19268
