Hurray for new fundamental domain checkerboards, and very kind to link equivalent tilings and duals in documentation! I don't actually know how to automate unique documentation with mass-uploading, except massive copy&paste sessions! [[User:Tomruen|Tomruen]] ([[User talk:Tomruen|talk]]) 19:47, 13 March 2013 (UTC)

p.s. With not too much work, I used an edge-filter to isolate out the 3 sets of ''mirrors'' [[:File:H2chess_246a.png]], [[:File:H2chess_246b.png]], [[:File:H2chess_246c.png]] into [[:File:642_symmetry_mirrors.png]]. Maybe this can be done via SVG and circle arcs someday, but nice to work with 2520 bitmaps for quality - just had to widen lines by softening and brightening. Anyway, this coloring shows what subsets of mirrors can be removed to generate another symmetry. If there are odd-orders, all the mirrors at those points get mapped to the same color, and must be all be removed in one step.
