E6 (mathematics)

In mathematics, E6 refers to a specific complex Lie group, which is part of a classification of simple Lie groups. The E6 group is one of the five exceptional simple Lie groups, and it has applications in various fields, including theoretical physics, particularly in string theory and particle physics. The E6 group is often represented in terms of its root system, which consists of 72 roots in an 8-dimensional vector space.
