1,8

Table of n, a(n) for n=1..85.

Some identities: a(n, k)=a(k, n); a(n, m*n)=a(n, m*n-1); a(n, n)=A000108(n-1); if n and k are coprime then a(n, k)=A071201(n, k)

Sequence in context: A109338 A291191 A273866 * A207379 A220163 A102715

Adjacent sequences: A071199 A071200 A071201 * A071203 A071204 A071205
