1. A rotation symmetry in dimension 2 or 3 must move a lattice point to a vectors in the figure.
2. Because all its faces have an even number of sides with 180 degree rotation symmetry, it is a zonohedron.
3. Note that these additional symmetries do not allow a planar slice to have, say, 8-fold rotation symmetry.
4. The cyclic groups may be obtained as rotation symmetries of polygons : the rotational symmetries of the digon provide the group C 2.
5. When describing the improper rotation symmetry element ( in 3 dimensional Euclidean space ) it is always specified that the reflection plane be perpendicular to the rotation axis.
6. It's difficult to find rotation symmetry in a sentence. 用rotation symmetry造句挺難的
7. This group is isomorphic to the dihedral group of order 6, the group of reflection and rotation symmetries of an equilateral triangle, since these symmetries permute the three vertices of the triangle.
