octaedron (octahedron) +‎ -icus (-al)



octaedricus (feminine octaedrica, neuter octaedricum); first/second declension

  1. octahedral, of or pertaining to an octahedron
    • 1611, Johannes Kepler, Strena seu De Niva Sexangula, p. 17:
      Nihil itague profecimus nisi pateat modus, guo calor internus guttam vapidam in tribus diametris, forma octaedrica vel certe sexangula firmet, ut ad eas fiat materiae per condensationem collectio.
      And so we have made no progress unless a way is open, in which the internal heat hardens the vaporous drop in three dimensions in an octahedral or certainly a six-angled shape, so that an accumulation of material can be made to them through condensation.


First/second declension.
