On the Encoding Method page I have replaced what was there with the first example of encoding and decoding.
This is Aldebaran, the label by the large star in the upper left pie slice of f68r3. Both encoding and decoding use the same letter table, with encoding taking place horizontally, and decoding vertically.
At the moment I have six other labels from f68r3 that encode and decode the same way.
There are still problems, such as there is no way of distinguishing which of the three letter value sets is used for a particular label other than trial and error. Also the problem of converting from Voynich letters to English letters. But I’m working on them.
Thoughts and comments requested.
