Subj: RE: Symmetry Operators
Hello Dipo,
Apologies for not reading your question carefully. I saw the last part and
at first assumed I had made a mistake, and then assumed that you wanted the
derivation for the Cartesian (which I then added in). I have never thought
about a generic symmetry operator derivation for general rectilinear (which
I think has an two "i"s as spelt?) coordinate systems, though I have thought
about the crystallographic cases involving axes of order 2, 3, 4, & 6.
I'll have a think about 5 (or 7), which do come up in protein crystallography
though only for local point group symmetry. Interesting question!
Best regards,
Jeremy Karl.
