COMMENTS

The SHC numbers are a subset of the HC numbers. Is there a formula for a(n) that depends on the two consecutive SHC numbers A002201(n) and A002201(n+1)?

EXAMPLE

Example: a(3)=3 because between the SHC numbers 12 and 60 there are three HC numbers: 24, 36 and 48.

CROSSREFS

Cf. A002182 (highly composite numbers), A002201 (superior highly composite numbers).
