Modular and Linear Fractional Groups,n this chapter we begin by describing the .-dimen-sional unimodular group ?., which is the group of automorphisms of the Abelian group ?.. or ?..,. For the special case when . = 2, we find the abstract definition .(7,29): . (1935b, p. 367) proved that when . > 3, ?. is the factor group obtained by a

Regular Maps,regular dodecahedron {5, 3} to obtain the star-polyhedron {./., 5} (. 1963a, pp. 49, 95–105) which is essentially a map of twelve pentagons on a surface of genus 4. The modern work on this subject received its impetus from two different sources: automorphic functions and the four-colour problem. Fro

rated group that the reader might propose. But we soon realized that more or less arbitrary restrietions are necessary, because interesting groups are so numerous. For permutation groups of degree 8 or less (i.e., .subgroups of 2: ), the reader cannot do better than consult the 8 tables of ]OSEPHINE

Crisis in the French Labour Movement definition for a given finite group. In § 2.4 we use it to find whether a given subgroup of an abstract group is normal. Finally, in § 2.5 we see how it helps in determining properties of new abstract groups.

Instead, for the sake of easier printing, we use lines drawn in various styles: ordinary, broken, dotted, etc. After suitably embedding the graph into a surface, we obtain a map from which a set of defining relations for the group may be read off.

Austerity and Extending the Racial State,prove that the generators may always be represented by real affine reflections, thus preparing the ground for a complete enumeration of the finite groups. Then we shall describe some of their remarkable properties.
