I would like to understand better the relation between
A072030 (number of steps in Nicomachus' algorithm) (see [1]) and
A113881 (smallest number of squares needed to tile an m x n rectangle).
What I mean can be easily seen by comparing the tables
http://oeis.org/A072030/table and http://oeis.org/A113881/table .
Is there a simple (not necessarily efficient) algorithm to compute A113881?
In particular I would like to know if the simple recurrence given in
A072030 can be used to advantage in computing A113881?
