Let m be a positive integer and let Ω be a finite set. The m-closure of GSym(Ω) is the largest permutation group on Ω having the same orbits as G in its induced action on the Cartesian product Ωm. The 1-closure and 2-closure of a solvable permutation group need not be solvable. We prove that the m-closure of a solvable permutation group is always solvable for m3.

可解置换群的 3-闭包是可解的

m为正整数,Ω 为有限集。的m -闭包G符号(Ω)是 Ω 上最大的置换群,其轨道与G对笛卡尔积的诱导作用相同Ω. 可解置换群的 1-闭包和 2-闭包不一定是可解的。我们证明可解置换群的m -闭包总是可解的3.
