• Expansion of e.g.f.: 1/(2-x-exp(x)).at n=6A006155
• Fibonacci sequence beginning 1, 32.at n=18A022402
• Consider sequence of fractions A066657/A066658 produced by ratios of terms in A066720; let m = smallest integer such that all fractions 1/n, 2/n, ..., (n-1)/n have appeared when we reach A066720(m) = k; sequence gives values of m; set a(n) = -1 if some fraction i/n never appears.at n=46A066849
