There are six reflective subgroup kaleidoscopic constructed from [8,6] by removing one or two of three mirrors.
A radical subgroup is constructed as [8,6*], index 12, as [8,6+], (6*4) with gyration points removed, becomes (*444444), and another [8*,6], index 16 as [8+,6], (8*3) with gyration points removed as (*33333333).
