The Korányi ellipsoidal ring,, is defined as the image of the Korányi spherical ring centred at the origin and of radiiandvia a linear contact quasiconformal mapin the Heisenberg group. Ifis the maximal distortion of, then we prove that the modulus ofis equal to\begin {equation*}\textrm {mod}(\mathcal {E})=\left (\frac {3}{8}\Big (K^ 2+\frac {1}{K^ 2}\Big)+\frac {1}{4}\right)\frac {\pi^ 2}{(\log (A/B))^ 3}.\end {equation*} References
