We show how one may classify all semisimple algebras containing the$\mathfrak{su}(3)\oplus \mathfrak{su}(2) \oplus \mathfrak{u}(1)$ symmetry ofthe Standard Model and acting on some given matter sector, enabling theoriesbeyond the Standard Model with unification (partial or total) of symmetries(gauge or global) to be catalogued. With just a single generation of StandardModel fermions plus a singlet neutrino, the only {gauge} symmetries correspondto the well-known algebras $\mathfrak{su}(5),\mathfrak{so}(10),$ and$\mathfrak{su}(4)\oplus \mathfrak{su}(2) \oplus \mathfrak{su}(2)$, but with twoor more generations a limited number of exotic symmetries mixing flavour,colour, and electroweak degrees of freedom become possible. We provide acomplete catalogue in the case of 3 generations or fewer and outline how ourmethod generalizes to cases with additional matter.
