Beginner resources for learning group theory and symmetry operations

[Kevin McHugh]

Hi folks,

I know nothing about groups or symmetry. Could anyone recommend a good introduction that defines groups and explains their notation and operations? I am particularly interested in general, orthogonal, and unitary groups.

Thanks in advance. Kevin

I would recommend "Groups and Symmetry" by Armstrong.

Being unemployed, I'd like to find a free e-book

Amazon in the USA has used copies (apparently in good condition) for less than $15 including shipping. A new paperback is about twice that price. Books are always a worthy investment.
