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}: . cinnamon roll teacher appreciation
