Sicherman dice

I've been sitting on this for a while. It seems to me to raise some interesting questions in combinatorics, and I'm not combinatoricist enough to really get a handle on them. If any of you have any relevant thoughts, or pointers to theory I've missed, or some such, I'd be interested in hearing.

What I've got is a text file. I could HTMLify it, or even just throw the whole thing into a <pre>, but the former requires a fair bit of work and a greater knowledge of HTML than I have, and even the latter requires some work, such as replacing `<' with `&lt;'. So I'm just going to link to the text file.

I will probably have more to say about this; even if nobody comes up with any remarks or pointers, I'll be poking around myself, and may come up with something I think worth saying. But if so that'll be a separate post, not edits to this one.
