论文摘要
我们表明，与Lie类型$ C_2 $关联的Steinberg Group $ \ text {st}（c_2，{\ mathbb z}）$，并且可以通过一个关系来实现整数系数。作为一个应用程序，我们给出了Symbletic模块化组$ \ text {sp} _4（{\ Mathbb Z}）$的新辫子样品。
We show that the Steinberg group $\text{St}(C_2,{\mathbb Z})$ associated with the Lie type $C_2$ and with integer coefficients can be realized as a quotient of the braid group $B_6$ by one relation. As an application we give a new braid-like presentation of the symplectic modular group $\text{Sp}_4({\mathbb Z})$.
