Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis. In addition to r… shuswap synthetic turfWebplane is denoted (Eq. 1). Correspondingly planes of this form ((212), (122), and negative index planes) are denoted by planes of a form: {hkl}, since for cubic crystals implicit in Fig. 1, planes are perpendicular to directions and have equiva-lent indices. It is common practice to denote both planes and directions by (hkl): [hkl] and {hkl}: . the owl house goa
