Distinguishing Characters

[nablator]

I don't know your anti-polybius theory, but is that based on knowledge of the polysius square? If so then it does have a source.

Not really, it is simple enough to have been invented independently. It has in common with the Polybius square that the ciphertext is a stream of alternated 2D coordinates xyxyxy... and the key is a square table. But instead of picking the cleartext letters at each (x, y) cell, it's the opposite, (therefore anti) they are picked between two vertices of the zigzag path defined by the stream of coordinates, leaving a lot of freedom when the original Polybius square cipher has none.

With multiple possible paths (= vords), there is sometimes no need to distinguish between r-s, o-a, y-q.
