Summary
DescriptionAntisymmetry operation.svg
English: By applying an anti-identity operation (1') to a white triangle a black triangle is created. A further application of the same antisymmetry operation converts the black triangle back to a white triangle. Two 1' operations are equivalent to a single identity operation (1) which leaves the original triangle unchanged. This type of operation is also referred to as black-white symmetry or dichromatic symmetry.
