You may notice that D4 and D8 have much
more easily discernable patterns than the others. Unfortunately, the reason
for this is beyond the scope of this paper. However, if we change the coloring
scheme so that all the rotations are colored blue/green and the flips are colored
red/purple, see what happens:

Although the triangles for some are always fuzzier than others (e.g. D4
and D8), all of the triangles exhibit the similarity to the
triangle for Z2 when rotations and flips are clearly distinguishable.
Again, this happens because when you lump all the flips together as if they
were the same element and you lump the reflections together as if they were
all the same, the resulting multiplication table is the same as that for Z2
with 0 replaced by the rotations and 1 replaced by the flips.
