To embed the bouquet of g circles \(B_g\) into the n-sphere \(S^n\) so that its full symmetry group action extends to an orthogonal actions on \(S^n\), the minimal n is \(2g-1\). This answers a question raised by Zimmermann.

要将g个圆的花束\(B_g \)嵌入到n个球体\(S ^ n \)中,以使其完全对称的群作用扩展到\(S ^ n \)上的正交作用 ,则最小n为\ (2g-1 \)。这回答了齐默尔曼提出的问题。
