COMMENTS

Minimum hook product over all partitions of n.

The minimum partitions are 1,2,21,31,311,321,3211.

LINKS

Table of n, a(n) for n=1..26.

EXAMPLE

For n=4, we can have;

abcd, abc and ab (the rest are symmetric).

......d.......cd

The hook products are 4!=24, 4.2.1.1=8 and 3.2.2.1=12, so a(4)=8.
