Abstract: We generalize to higher dimensions the classical Stoïlow factorisation theorem; we show that any quasiregular mapping $ f$ of the Riemann $ n$-sphere $ \hat{\mathbb{R}}^n \approx \mathbb{S}^n$ can be written in the form $ f=\varphi \circ h$, where $ h:\mathbb{S}^n \to \mathbb{S}^n$ is quasiconformal and $ \varphi$ is a uniformly quasiregular mapping, hence rational with respect to some bounded measurable conformal structure.
