... × In geometry, an ''n''-orthotope〔Coxeter, 1973〕 (also called a hyperrectangle or a box) is the generalization of a rectangle for higher dimensions, formally defined as the Cartesian product of intervals. ==Types== A three-dimensional ''orthotope'' is also called a right rectangular prism, rectangular cuboid, or rectangular parallelepiped. A special case of an ''n-orthotope'', where all edges are equal length, is the ''n-cube''. By analogy, the term "hyperrectangle" or "box" refers to Cartesian products of orthogonal intervals of other kinds, such as ranges of keys in database theory or ranges of integers, rather than real numbers.〔See e.g. .〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「hyperrectangle」の詳細全文を読む スポンサード リンク
