COMMENTS

This is always an integer for n>=2.

a(n) = 1 for n in A111315. When this happens A109890(n+1) makes a large jump. The corresponding values of A109890(n+1) are in A111316 (cf. A111242).

a(n) = A094340(n) for all n > 1. [From David Wasserman, Jan 06 2009]

LINKS

EXAMPLE

A109735(4)=12, A109890(5)=4, so a(4) = 12/4 = 3.
