ii on iii, & iii on i, & so on. (The arc
here measures 120 [degrees].)
(11) However the cords are numbered
& in whichever direction the cords
are twisted, the resulting Torsion
Knot will be the same, except that
reversing the direction of twisting
gives the reverse form of the knot. Hence
it is not necessary to distinguish
the individual cords by numbers.
(iii) The twisting must begin on the
untwisted cords & continue for the
required number of arcs uniformly
in the same direction.
(iv) Torsion Knots can be arranged in
series taking their index numbers
from the number of original untwisted
parallel equidistant cords, & these series
are K 1, K2, K 3 & so on to K [infinity].
