Ray Chandler, Table of n, a(n) for n = 1..10000

FORMULA

a(n) = A046087(n) - A046086(n) = A118962(n) - A118961(n).

MATHEMATICA

A[s_Integer] := With[{s6 = StringPadLeft[ToString[s], 6, "0"]}, Cases[ Import["https://oeis.org/A" <> s6 <> "/b" <> s6 <> ".txt", "Table"], {_, _}][[All, 2]]];

A046086 = A@046086;

A046087 = A@046087;

a[n_] := A046087[[n]] - A046086[[n]];

a /@ Range[10000]; (* Jean-Fran├žois Alcover, Mar 07 2020 *)
