Groups of Knots.
In Plait Knots the sequence of
like crossings (i.e. over or under)
is 1, equivalent to saying they are
alternate.
In Torsion Knots it is x-1 over
x-1 under & so on.
This suggests that knots may be
arranged in a number of series
according to the sequence of their
crossings, thus
n (= an indefinite no, indicating a series.)
Torsions n-1
n-2
n-3

n-(n-2)=2
