由一个拟群(Q, )可以定义出6个共轭拟群,这6个共轭拟群不一定互不相同,其构成的集合C(Q, )的基数t可能的取值是1,2,3或6.记q(n,t)是所有满足│C(Q, )|=t的n阶拟群的个数,本文利用完全3部图Kn,n,n的三角形分解来考虑q(n,1)和q(n,3)的计数问题.
We can define six conjugate quasigroups from a quasigroup (Q, ). These six conjugate quasigroups are not necessarily distinct. The number of distinct conjugates of a quasigroup is always 1, 2, 3 or 6. Denote the set of the conjugates of a quasigroup (Q, ) by C(Q, ), and the number of aIi quasigroups of order n satisfy |C(Q, )| = t by q(n, t). In this paper, we count the q(n, 1) and q(n, 3) by using triangle decomposition of 3-patite complete graph Kn,n,n.
