摘要：In this paper,the $n$-Gordian complex of knots is defined which is an extention of the Gordian complex of knots.The authors show that if $n \ge 2$ and $n$ is even,then for any knot $K$ and any positive integer $r$,there is a finite set of knots of size $r$ containing $K$,such that the $n$-Gordian distance between any two knots in this set is 1.
