==Simply laced groups<!--'Simple Lie groups' redirects here-->==
A '''simply laced group''' is a [[Lie group]] whose [[Dynkin diagram]] only contain simple links, and therefore all the nonzero roots of the corresponding Lie algebra have the same length. The A, D and E series groups are all simply laced, but no group of type B, C, F, or G is simply laced.
