摘要
张远达在其著名著作《有限群构造》中证明了定理4(见引言),并明确指出条件[G:N_G(H)]为有限数是关键。本文证明了这个条件可以去掉,并得到更一般的定理。
Prof. Chang Yuanda proved Theorem 4 in his well-knownbook 'Structure of Finite Groups' (in Chinese) (P.49). and pointed out that the condition that [G:NG(H)] is finite was the key of the theorem. In this note, it is shown that the codition can be left out, and a more general theorem has been proved.
