text: # Steinberg group
  
  In mathematics, Steinberg group means either of two distinct, though related, constructions of the mathematician Robert Steinberg:
  
  * Steinberg group (K-theory) St(A) in algebraic K-theory.
  * Steinberg group (Lie theory) is a 'twisted' group of Lie type, in particular one of the groups of type $^3D_4$ or $^2E_6.$
