ἐπίτριτος δὲ λέγεται ἀριθμὸς ὁ ἐξ ὅλου τινὸς ἀριθμοῦ συνεστηκὼς καὶ ἐκ τοῦ τρίτου μέ- ρους ἐκείνου, ὡς ἔχει ὁ ὀκτὼ πρὸς τὸν ἕξ καὶ γὰρ αὐτὸν τὸν ἓξ περιέσχηκε καὶ τὸ τρίτον αὐτοῦ, τουτέστι τὴν δυά- δα. ἡμιόλιος δὲ καλεῖται, ὅταν περιέχῃ ἀριθμὸς ἀριθμὸν καὶ τὸ ἥμισυ ἐκείνου, ὡς ἔχει ὁ ἐννέα πρὸς τὸν ἕξ· συν- έστηκε γὰρ ἐκ τοῦ ἓξ καὶ ἐκ τοῦ ἡμίσεος αὐτοῦ, τουτέστι τῶν τριῶν. διπλασίων δέ προσαγορεύεται ὁ δυσὶν ἀριθμοῖς 〈ἴσοις〉 ἴσος, ὡς ὁ τέσσαρα πρὸς τὸν δύο δὶς γὰρ τὸν αὐτὸν περιέσχηκεν.
