论文摘要
我们描述了用单肌组PSL的4分单位合理函数的一个4分点合理函数家族的明确计算（6,2）。尤其是，这是否定的。计算的家族还引起了Q（t）上AUT（PSL（6,2））的非规范学位-126实现。
We describe the explicit computation of a family of 4-branch-point rational functions of degree 63 with monodromy group PSL(6,2). This, in particular, negatively answers a question by J. König whether there exists a such a function with rational coefficients. The computed family also gives rise to non-regular degree-126 realizations of Aut(PSL(6,2)) over Q(t).
