From the reviews of the French edition "This is a rich and useful volume. Thematerial it treats has relevance well beyond the theory of Lie groups and algebras, ranging from the geometry of regular polytopes and paving problems to current work on finite simple groups having a (B,N)-pair structure, or "Tits systems". A historical note provides a survey of the contexts in which groups generated by reflections have arisen. A brief introduction includes almost the only other mention of Lie groups and algebras to be found in the volume. Thus the presentation here is really quite independent of Lie theory. The choice of such an approach makes for an elegant, self-contained treatment of some highlyinteresting mathematics, which can be read with profit and with relative easeby a very wide circle of readers (and with delight by many, if the reviewer is at all representative)."
