Hi Martin, In 2006 you made some really great Euclidean plane wallpaper group diagrams. Your diagrams replaced some crude markups I colorizd from a book. I'm in the process of testing out some parallel diagrams for *642 hyperbolic symmetry. [[:File:Tetrahexagonal_tiling_subgroups.png]] just hand-made in MSPaint, using [[:en:Coxeter notation]] for subgroups and [[:en:Orbifold notation]] for resulting group. I'm still looking into the locations of the glide reflections, so those are not all correct. Anyway, I'm curious if you could make some SVGs like this. I drew a partial hyperbolic tiling of *642 as a straight-line [[:en:Beltrami–Klein model]], but might be more clear inside a hexagon with circle arc edges of [[:en:Poincaré disk model]]. What do you think? Is this something you're interested in? I see some incomplete hyperbolic work from [http://www.morenaments.de/hyp/].
