Great stuff!

By the way, what would you and Carl think of starting a web ring? You
only need four websites for a webring.com website.

I don't have a site, yet. But I also prefer just linking to
friends in the conventional way, or using google's similar
pages feature.

Great stuff, indeed. That's everything I've ever suspected,
and more.

Nice indeed. Was the formula p(n) = floor(na/b) proven by Clough and
Douthett?
Because I remember the definition being in terms of interval sizes.

I don't have that paper. I got it from equation 1.1 in Aytan Agmon's 1996 one. He says in Note 17 "In theorems 1.2 and 1.5 Clough and Douthett establish that 'being a J-set' (Definition 1.9) is equivalent to 'having the property that the spectrum of each dlen is either a single integer or two consecutive integers' (Definition 1.7). Thus Clough and Douthett's 'maximal evenness' ... and the present relation (1.1) are the same ..."

Ah, so Agmon proved it then, good.
