I'd have to agree with Saptarshi / Matthew on this one. I enjoy seeing example implementations (if clearly done), and presumably these more esoteric combinatorial objects have been contrived for one reason or another -- better properties in certain cases, etc. I think they're suited for the combinatorics module (nothing wrong with doing advanced combinatorics), but at the very least they should be shipped with sympy in an "example implementation" directory.
