In the family ***p*,*q*,*r* (*p* ³
*q* ³ *r *³ 2)
we have three-component links for *p* = *q* = *r* = 0 (*mod* 2),
two-component links if exactly one of the numbers *p*,*q*,*r* is odd,
and knots if at least two of them are odd. All the properties of the links obtained
are regularly distributed: their Alexander polynomials, unknotting numbers, etc.
For example, for the knots from this family we have the
following abbreviated Alexander polynomials and
unknotting numbers:
**
3,3,2 1-3+4-5 2

5,3,2 1-3+4-5+5 3
7,3,2 1-3+4-5+5-5 4
9,3,2 1-3+4-5+5-5+5 5
3,3,3 7-13 3
5,3,3 10-19 3
7,3,3 13-25 3
9,3,3 16-31 3
4,3,3 2-5+6-7 3
6,3,3 3-7+8-9 3
8,3,3 4-9+10-11 3
