/ˈˌɔrθoʊsəˈmɛtrɪk(ə)l/

Origin: Formed within English, by compounding. Etymons: ortho- comb. form, symmetrical adj.

Etymology: < ortho- comb. form + symmetrical adj. In sense 1 after orthosymmetry n. Compare slightly later orthosymmetric adj.

rare.

†1. Crystallography. Symmetrical about perpendicular axes; = orthosymmetric adj. 2. Obsolete.

1880 R. F. Scott Treat. Theory Determinants vi. 78 Such determinants have been called orthosymmetrical. Their most important property is that we can replace the elements by differences of a₁.

1923 Amer. Math. Monthly 30 197 Although it belongs to the class of determinants sometimes called orthosymmetrical, and specially studied by Hankel, the principal theorem relating to this class of determinants is not directly effective.
