I don't think I really have 40 different methods, and they're mostly not original to me.
Using 2/3 at least would be more historically accurate if less aesthetically pleasing. However there is no 5-term series for 732/733 using 2/3, it requires six, e.g.
(The requirement for six terms follows easily from the facts that 732/733 needs seven unit fractions and that 2/3 or 3/4 can be expanded into two unit fractions each.) -- David Eppstein UC Irvine Dept. of Information & Computer Science firstname.lastname@example.org http://www.ics.uci.edu/~eppstein/
