%N Number of highly composite numbers between two consecutive superior highly composite numbers.

%C 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)?

%H Amiram Eldar, <a href="/A113069/b113069.txt">Table of n, a(n) for n = 1..4252</a> (Calculated from Achim Flammenkamp's List of the first 779,674 highly composite numbers)

%H Achim Flammenkamp, <a href="http://wwwhomes.uni-bielefeld.de/achim/highly.html">Highly Composite Numbers</a>.

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

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