Voynichese is a numeric cipher?

[ololololo]

Of course, it is still possible that the Voynich writing system may have allowed a much wider range of glyph combinations and positional rules than those found in the manuscript. We can only infer rules from the sequences that happen to appear. Perhaps the source material, if there was any, simply had no need for the other possibilities.

The situation, apparently, is exactly as it appears to be...
But it will still be useful to at least study this cipher. Again, I think it wasn’t invented by a brilliant cryptologist, which means it may be complex and redundant, but not that brilliant.
