Let \( G \) be a periodic group, and let \( \omega(G)\subseteq{} \) be the spectrum of \( G \) that is the set of orders of elements in \( G \). We prove that the alternating group \( A_{7} \) is uniquely recognized by its spectrum in the class of all groups.

通过其元素顺序集识别$ A_ {7} $
让\(G \)是周期性组,并且让\(\欧米加(G)\ subseteq {} \)是的频谱 \(G \) 是集合中的元素的顺序的 \(G \)。我们证明了交替组\(A_ {7} \)在所有组的类别中被其频谱唯一识别。
