Several new results concerning \(6j\)-symbols are established and proved. It is shown that the elliptic \(6j\)-symbols have tetrahedral symmetry analogous to the well-known symmetry of the classical and quantum \(6j\)-symbols. Using a graphical calculus a relation between the elliptic \(6j\)-symbols and the trigonometric \(6j\)-symbols is established. The transformation properties of the elliptic \(6j\)-symbols under the natural action of the modular group \( SL_{2}\left( {\mathbb Z}\right) \) in the space of parameters are given.
