Inside the Voynich Network: graph analysis

[Rafal]

Its words form tightly bound groups that repeat with remarkable regularity

I wonder how could it be as VM doesn't have repeated sentences and doesn't seem to have any regularity when watched with a "naked eye".

I can imagine such groups for example in prayers:

Mother of good counsel, pray for us.
Mother of our Creator, pray for us.
Mother of our Savior, pray for us.
Virgin most prudent, pray for us.
Virgin most venerable, pray for us.
Virgin most renowned, pray for us.

But VM doesn't have such a thing.

Are these groups something more subtle and abstract? How do they work?
Does your method allow to find and show some concrete examples of such regularity?
