Groups of transformations I tried to find literature and articles about groups of transformations, but mostly what I found is either about groups or about transformations. 
Can you suggest me literature where groups of transformations are described. Specifically I'm interested in groups of linear and orthogonal transformations. 
P.S. I'd prefer books and articles in Russian.

Mark A. Armstrong - Groups and Symmetry is definetely one of what you are looking for.
