(a)
Interpretation:
Whether the given combination of symmetry operations constitutes a complete group or not is to be determined. The missing symmetry operation(s) are to be supplied if the given combination does not constitute a complete group.
Concept introduction:
A symmetry operation is defined as an action on an object to reproduce an arrangement that is identical to its original spatial arrangement. The group of symmetry operations of which at least one point is kept fixed is called point group. The symmetry operations can be identity, rotation, reflection, inversion and improper rotation.
(b)
Interpretation:
Whether the given combination of symmetry operations constitutes a complete group or not is to be determined. The missing symmetry operation(s) are to be supplied if the given combination does not constitute a complete group.
