  We briefly review 3-dimensional untwisted Dijkgraaf-Witten theory over a
finite group $\Gamma$, and present a method of computing untwisted
Dijkgraaf-Witten invariants for arborescent links. Some explicit formulas are
given when $\Gamma=\mathbb{Z}/p\mathbb{Z}\rtimes\mathbb{Z}/(p-1)\mathbb{Z}$ for
an odd prime $p$.
