(vi.) All other ^ reduced knots are irregular
(vii.) The regular knots can be arranged
in series taking their index numbers
from the number of parts traversed by
a radius of the circle ^ (v) & those series
are S1, S2, S3, S4, &c to S[infinity sign]. Hence
any series, Sx, will show in all the
diagrams of knots belonging to it, n
parts lying round the centre of the
circle. n is always a positive integer.
(viii) It is convenient, though not ne-
cessary, to take account of the bights
formed by the parts in going from
next ^ nearest the circumference of
the circle to the next similar crossing.
For shortness, bights are written B, and
crossings (always alternate) C. B & C are
always positive integers.
