Overall, this was a well-written paper. An impressive piece of work for
undergraduates. The authors might do the following, especially for the
benefit of fellow undergraduates. At the beginning, include something
like:
The algebraic notation and definitions in this paper, unless otherwise
noted, follow that of {book; Hungerford? Gallian? (although it did not
contain a definition of indirect product)}. If the defintion is not in
the said text (which, of course, would be footnoted), then the term
should be defined in the text. It would enhance the reader's
comprehension.
Thank you for the opportunity, and sorry that my report is a bit late.
