Based on the second isomorphic theorem and properties of the symmetric group
a theorem is proposed to construct one Sylow-p group of symmetric group by adding generators to p-group.The additive generators we choose can ensure to obtain Sylow-p subgroup quickly.And then all the conjugate subgroups can be derived.The properties of normalizers is adopted to find an element that persuade one Sylow-p subgroup conjugates to another
and this can avoid redundancy checking.When applying to S

experiments show that this algorithm enjoys both easy implementation and low time complexity.
