??so what about "integral surfaces of higher-degree distributions" and so forth, and relationship to "pfaffian geometry" (and so forth...)?? ... hmm, but the pfaffian stuff as i understand it is just for integrable distributions, right?? ...or something like that... hmmm... simplicial interpretation.... ???there _is_ a "higher-degree" aspect, though, isn't there???.... not sure... i'll have to think about this....
