Web1.3.3.3. Symmorphic and non-symmorphic space groups If a coset with respect to the translation subgroup contains an operation of the form ðW;wÞ with w a vector in the translation lattice, it is clear that the same coset also contains the operation ðW;oÞ with trivial translation part. On the other hand, if a coset javascript pptx to htmlWebSince nonsymmorphic groups are actually more numerous than symmorphic groups and crystals with these symmetries occur extensively in nature (for example, the diamond lattice), these results may have widespread applicability.
