Generalizations: the generalized antipodes of multi-ring edos

m TallKite moved page Antipodes to Kite's thoughts on antipodes: Editor VectorGraphics has repeatedly edited pages I've written about my own research and inserted misinformation. On discord he is openly hostile to me. This move is necessary to avoid a toxic work environment for me.

* If the edo is odd and the 5th is even, the antipodes are the mid-3rd (half-5th) and its octave complement a 4th higher. For example, [[17edo]]'s 5th is 10\17, and its antipodes are 5\17 and 12\17.
* If the edo is odd and the 5th is even, the antipodes are the mid-3rd (half-5th) and its octave complement a 4th higher. For example, [[17edo]]'s 5th is 10\17, and its antipodes are 5\17 and 12\17.


In summary, the antipode is always the half-octave, the half-4th or the half-5th, whichever one exists in the edo. The proof that one and only only one of these will exist in any single-ring edo is left as an exercise for the reader.
In summary, the antipode is always the half-octave, the half-4th or the half-5th, whichever one exists in the edo. Only one of these exists; or all three exist, in which case the edo is multi-ring.

While not all edos have conventional antipodes, all edos have generalized antipodes. For every even edo, the generalized antipodes is always the half-octave. For example, 24edo has generators 1\24, 5\24, 7\24 and 11\24 (plus their octave complements). In all 4 circles of generators, the farthest point is 12\24.
