Let \( G \) be a periodic group and let \( \omega(G) \) be the spectrum of \( G \). We prove that if \( G \) is isospectral to \( A_{7} \), the alternating group of degree \( 7 \) (i.e., \( \omega(G) \) is equal to the spectrum of \( A_{7} \)); then \( G \) has a finite nonabelian simple subgroup.

在等价于$ A_ {7} $的周期群上。II

\(G \)为周期群,令 \(\ omega(G)\)\(G \)的谱 。我们证明如果\(G \)\(A_ {7} \)等谱,则度数\(7 \)的交替组(即\(\ omega(G)\)等于 \ (A_ {7} \)); 那么 \(G \)有一个有限的非阿贝尔简单子群。
