论文摘要
我们描述了伪分割的直接结构，绝对是伪简单的最小型组，具有$ bc_n $类型的不可约根系统；这些仅在特征$ 2 $中存在。我们还为其不可还原模块的尺寸提供了一个公式。
We describe a straightforward construction of the pseudo-split absolutely pseudo-simple groups of minimal type with irreducible root systems of type $BC_n$; these exist only in characteristic $2$. We also give a formula for the dimensions of their irreducible modules.
