Snub square tiling coloring as pg This coloring of the snub square tiling was listed as pg but I can t find the glide reflections I only see translations so it looks like p1 to me Also pg would imply one set of parallel glides while symmetry here would more imply two orthogonal sets like pgg but with a 2 fold rotation while there are no gyration points either Can anyone help class wikitable width 480 One of the colorings of the snub square tiling the glide reflection lines are in the direction upper left lower right ignoring colors there is much more symmetry than just pg then it is p4 mg see there for this image with equally colored triangles It helps to consider the squares as the background then we see a simple patterns of rows of rhombuses
