  This document is the first iteration of an attempt to collate information
about small-rank groups of Lie type over small fields, and their representation
theory over the defining field. This information is important in the author's
work on subgroup structure of exceptional groups of Lie type. The most
important information in that work is information about $\mathrm{Ext}^1$
between simple modules, and so in Version 1 of this document, that data is
almost all of the data available. In addition, a lot of information about the
dimensions of the simple and Weyl modules is included. More generally, one may
expect to include details about the socle structure of the projective modules,
Jordan block structure of the action of unipotent elements, decompositions of
symmetric and exterior powers of simple modules, and tensor products of
modules, traces of semisimple elements and so on. The ideal place for such
information is a dedicated website, connected to a database that could be
queried to produce the information required. This document, while imperfect,
will have to suffice for now.
