Cayley Graph on Symmetric Group Generated by Elements Fixing $k$ Points

Kok Bin Wong, Terry Lau, Cheng Yeaw Ku

Let $S_{n}$ be the symmetric group on $[n] = {1, \dots, n}$ . The $k$ -point fixing graph $F (n, k)$ is defined to be the graph with vertex set $S_{n}$ a…

An Erd{\H o}s-Ko-Rado theorem for permutations with fixed number of cycles

Cheng Yeaw Ku, Kok Bin Wong

Let $S_{n}$ denote the set of permutations of $[n] = {1, 2, \dots, n}$ . For a positive integer $k$ , define $S_{n, k}$ to be the set of all permutations of $[n]$ with exactly $k$ disjo…
