Die Punktgruppen,e durch Bausteine, so müssen die Bausteine — wenn die Raumgruppe erhalten bleiben soll — mindestens die gleiche Symmetrie aufweisen wie die Gitterpunkte. Die Symmetrie eines Gitterpunkts ist einfach aus der Raumgruppe abzuleiten. Man muß nur alle die Punktsymmetrieelemente der Raumgruppe berücksichtMotilin 发表于 2025-3-25 13:33:30

Die äquivalenten Punkte einer Punktlage müßten vollständig, und zwar durch Bausteine gleicher Art besetzt sein.

After finishing his comparative study and family classification of the monocots, h
