This paper gives a uniform method of constructing generators for matrix representations of finite groups of Lie type with particular emphasis on the exceptional groups. The algorithm constructs matrices for the action of root elements on the lowest dimension representation of an associated Lie algeb

โฆ Synopsis
In 1962 Steinberg gave pairs of generators for all finite simple groups of Lie type. In this paper, for each finite orthogonal group we provide a pair of matrices which generate its derived group: the matrices correspond to Steinberg's generators modulo the centre. These generators have been implemented in the computer algebra system MAGMA and this completes the provision of pairs of generators in MAGMA for all (perfect) finite classical groups.

In recent years an increasing amount of our knowledge about finite groups, and especially the sporadic simple groups, has been obtained by computer calculations. This has many advantages over more traditional methods, especially speed and accuracy, and problems can be solved that are out of reach of
## Abstract We show (under some hypothesis in small dimensions) that the analytic degree of the divisor of a modular form on the orthogonal group O(2, __p__) is determined by its weight. Moreover, we prove that certain integrals, occurring in Arakelov intersection theory, associated with modular fo
