Thanks Richard - I sort of realized that - and your comments basically mirror those of the reviewers. On the other hand I quite like the idea of RK formulas developed by CAS, in which there is a small literature. One possible approach might be to use Sage also to generate the RK formulas using Butcher's tree-based methods, and compare the two methods somehow. Anyway, I hate throwing material away; I wonder if I can somehow re-engineer the material to be more education focused?
