Lemmata on maximal subgroups
International Tables for Crystallography (2011). Vol. A1, Section 1.2.8.2, pp. 23-24 [ doi:10.1107/97809553602060000791 ]
Lemmata on maximal subgroups 1.2.8.2. Lemmata on maximal subgroups Even the set of all maximal subgroups of finite index is not finite, as can be seen from the following lemma. Lemma 1.2.8.2.1.The index i of a maximal subgroup of a space group is always of the form , where p is a ...
General lemmata
International Tables for Crystallography (2011). Vol. A1, Section 1.2.8.1, p. 23 [ doi:10.1107/97809553602060000791 ]
General lemmata 1.2.8.1. General lemmata Lemma 1.2.8.1.1.A subgroup of a space group is a space group again, if and only if the index is finite. In this volume, only subgroups of finite index i are listed. However, the index i is not restricted, i.e. there is no number I with the ...
Lemmata on subgroups of space groups
International Tables for Crystallography (2011). Vol. A1, Section 1.2.8, pp. 23-24 [ doi:10.1107/97809553602060000791 ]
Lemmata on subgroups of space groups 1.2.8. Lemmata on subgroups of space groups There are several lemmata on subgroups of space groups which may help in getting an insight into the laws governing group-subgroup relations of plane and space groups. They were also used for the derivation and the checking ...
