Green, Richard M. Representations of Lie algebras arising from polytopes. (English) Zbl 1234.17005 Int. Electron. J. Algebra 4, 27-52 (2008). Summary: We present an extremely elementary construction of the simple Lie algebras over \(\mathbb C\) in all of their minuscule representations, using the vertices of various polytopes. The construction itself requires no complicated combinatorics and essentially no Lie theory other than the definition of a Lie algebra; in fact, the Lie algebras themselves appear as by-products of the construction.
