Voynich anagramming

[doranchak]

There is also a huge difference in the counts of each group size.
For example:

[korol, kolor, oklor, olkor] (1, 1, 1, 4):  has group size 4.
[kchedy, kechdy, chedky, ykched, ckhedy, chkedy] (22, 4, 1, 1, 4, 5):  has group size 6.

Here are the totals for each group size, for Voynichese:

{1=4650, 2=845, 3=279, 4=106, 5=46, 6=22, 7=3, 8=4, 9=3, 10=2, 15=1}

And for English:

{1=7382, 2=306, 3=24, 4=3}

Observations:

• There is a much larger variety of anagram group sizes in Voynichese compared to English.
  
• Only 58% of vords are NON-anagrammable, compared to 91% of English words.
  
• There are anagram groups of size 10 and 15 in Vonichese but none of sizes 11 through 14.
  

The anagrams are just vords with edit distance of zero.  Hasn't edit distance analysis already been done?
