comment Is this way of teaching how to solve equations dangerous somehow?
@jk. The second way does not teach you much. This question is not about how to solve an equation. My point is that the first way teaches the students better.

comment What is the class of languages accepted by DFAs whose transition monoids are transitive permutation groups?
@HendrikJan Is every permutation group transitive? Your question is part of my question. Is it a proper subclass of p-regular language?

Thanks for the info of Kilp and Knauer's book. I did not know that book. However, I am not that interested in wreath product. Do you happen to know some info about direct product of semiautomata? Thanks again.
