IUCr 1994 Report - Volume `A1'. Maximal Subgroups of Space and Plane Groups

This a companion to Volume A, in which the data on subgroups in Volume A are extended and completed as follows:

(i) All maximal subgroups of index 2, 3 or 4 are listed individually and not only by type.

(ii) All maximal subgroups of index > 4 are listed implicitly as members of infinite series (these subgroups are always isomorphic).

(iii) All subgroups are listed either by their general positions or by a set of generators.

(iv) The matrix for the basis transformation and the column for the origin shift are added in short form.

(v) Conjugate subgroups are connected by a curly bracket.

The subgroup data for Volume A1 are essentially completed and will be transmitted to the Technical Editor in electronic form (LaTeX).
