I tried this about 20 years ago, selecting methods at random with the 
required lead heads, but never got beyond about 12 mutually true 
methods. When I last spoke to Roddy Horton he was also investigating 
similar ideas.

With a seven-part you can quite quickly find a set of methods that fit a 
given composition (especially using SCAMP). The problem with more 
general arrangements is that there are many more distinct relationships 
between the lead-heads of a pair of methods, hence possibilities for 
cross-falseness that have to be avoided. Colin Wyld's 24 works because 
the methods were carefully chosen.
