I'm going to be teaching an introductory abstract algebra....

... I'd prefer using G.A.P...

Dear Prof. Kaustuv M. Das,

This mail may not answer your question properly:

>if anyone knows of any books out there for such a course...

However for these two or three years I also have been using gap

in my algebra classes.

Gap has a very precise manual in its. You can refer it by netscape, lynx etc.

If your gap is gap3r4p4 then the manual starts from ./gap3r4p4/htm/index.htm.

Most of my students are Japanese and find it difficult to read the manual

in a limited time, but I think first several chapters are already good

introduction to gap.

I use gap for letting my students to understand algebras which are used

in cryptography. I started my class from elementary number theory using

PowerMod, ChineseRem,.. functions, then group theory introducing

functions ConjugacyClasses, IsAbelian, Subgroup, RightCosets, and so on.

Finally I explaind discrete logarithm problem and showed them a programme

of computing large prime fields by gap.

Though it is time consuming to prepare the classes, but most of my

students filled the questionnaires very positively.

(ref. GAP in algebra class. Proceedings of the third Asian technology

conference in mathematics, ATCM '98, Springer(1998)233-245)

Therefore I believe that your students also would enjoy your class

very much.
