We discuss two corrections concerning the paper mentioned in the title. One of them pertains to a slight error in a statement from a different paper that was used. For this statement, it is explained how to fix it and why this does not affect the correctness of our results. The other is concerned with an error in the original GAP source code used to verify some of our results. This error, which was subsequently fixed, did affect the correctness of one of our main theorems, which is now given in corrected (and stronger) form.

我们讨论了关于标题中提到的论文的两个更正。其中一个与使用的另一份论文的声明中的一个小错误有关。对于此语句，解释了如何修复它以及为什么这不会影响我们结果的正确性。另一个涉及用于验证我们的某些结果的原始 GAP 源代码中的错误。这个错误，随后被修复，确实影响了我们的一个主要定理的正确性，现在以更正（和更强）的形式给出。
