The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.

Original Wikitext content:

=Theorems= 
* Every triple Fokker block is max variety 3.
* Every max variety 3 block is a triple Fokker block.
* Triple Fokker blocks form a trihexagonal tiling on the lattice.
* A scale imprint is that of a Fokker block if and only if it is the [[product word]] of two DE scale imprints with the same number of notes. See <span style="background-color: #ffffff; color: #1155cc; font-family: arial,sans-serif;">[[@http://www.springerlink.com/content/c23748337406x463/]]</span>
* If the step sizes for a rank-3 Fokker block are L, m, n, and s, where L > m > n > s, then the following identity must hold: (n-s) + (m-s) = (L-s), hence n+m=L+s
* Any convex object on the lattice can be converted into a hexagon.
* Any scale with 3 step sizes is a hexagon on the lattice, in which each set of parallel lines corresponds to one of the steps.

=Unproven Conjectures= 
* Every rank-3 Fokker block has mean-variety < 4, meaning that some interval class will come in less than 4 sizes.
