OEIS Sequences

For every positive integer m, let u(m) = (d(1),d(2),...,d(k)) be the unitary divisors of m. The sequence (a(n)) consists of integers of the form d(k)/d(1) + d(k-1)/d(2) + ... + d(k)/d(1). A229999

a(0)=1, a(1)=1, a(n) = 17·a(n/2) for n=2,4,6,..., a(n) = 16·a((n-1)/2) + a((n+1)/2) for n=3,5,7,.... A116523
