Absence of the Symbol Resembling '4' in the Very First Folio 1r

[Mark Knowles]

A more ambitious project would be to look at every Voynichese symbol even the rare ones, just because they are rare doesn't make them less relevant for these purposes, and in which surviving ciphers they occur that would mean enciphered letters, cipher ledgers and manuscripts with ciphers in them. That could give one a map of commonality. I have plenty to follow up from my Milan trip so I can't put the time into this at the moment.
