Idea

The exceptional Lie groups are the exceptional structures among the simple Lie groups.

The classification of simple Lie groups consists of four infinite series – the classical Lie groups, and five exceptional Lie groups, called

On the level of Kac-Moody Lie algebras/Kac-Moody groups the E-series continues as
