The Impossibility of Double Gallows

[nablator]

In some of the examples nablator points out, the character looks like a z. In others, it looks more like an m.
For example, the 69v one and the 70v outer ring one don't feature the descending long tail that m has, so I was inclined to think they could indeed be z. Later, on f70v, the other z that nablator points out is (to me) clearly an m.

Thanks for the review, I had these in my files from a previous (quick) pass, not yet finalized, so I have to revise these. Rare glyphs are not a pressing issue anyway because they don't matter in statistical analysis.

Interestingly, it appears that double m is also rare but possible; voynichese.com (and therefore takahashi) records two occurrences of double m:
daimm on 3r (that one I agree is definitely a double m) and damamm (which actually looks to me more like dazazm ) on 67v1.

On 3r it is clearly daimg IMHO, therefore not repeated.
