设为具有q个元素的有限域,并设为上的置换多项式。记上的对称群。在这篇文章中,我们主要研究了三阶元的一些刻画,即文献中也称为三圈置换。构造了一些显式三圈置换。
Letbe the finite field withqelements and letfbe a permutation polynomial over. Letdenote the symmetric group on. In this paper, we mainly investigate some characterizations on the elementsof order 3, i.e.,, wherefis also called a triple-cycle permutation in the literature. Some explicit triple-cycle permutations are constructed.
