If one takes a look below next to where the red dots are in the attached, one will see a numerical figure (i.e, 1, 2, 3 or 4) after the knot type description.
For instance AS3 or Sy1, etc. I know what the letters mean / stand for, but what does the numeral stand for / mean in relation to the knot then? I cant find it described anywhere else in his book.
Thanks in advance for any help!

Anyway, re the numeral 1 (as in say AS1) meaning one strand. Would that one strand be made up of several threads plied together (to make that one strand) then?
