I am self-educating my self, late in life,  in higher math and had hit a wall with grasping the subtleties of group theory.  This book was right on the money about what I need, which is much more than a surface introduction, yet still written for those who need fundamentals explained in plain English.  Much to my delight Pinter turned out to be a "real human being" who apparently wrote the book out of a genuine interest in getting a working familiarity with the upper reaches of algebra (especially group theory) over to others.<br><br>Each chapter concludes with exercises that re-enforce that ground just covered, which is very useful for those of us whose understanding is easily forgotten.<br><br>Lucky me.
