On the Homotopy type of the Classifying Space 
         of the Exceptional Lie Group of Rank 4 


Previous work of several authors shows that the exceptional 
Lie group of rank 4, F_4, as a p-compact group, is determined 
up to isomorphism by the isomorphism type of its maximal torus 
normalizer for p>2. This paper considers the case p=2 proving 
that F_4 as 2-compact group is also determined up to isomorphism 
by the isomorphism type of its maximal torus normalizer. This 
allow the authors to determine the integral homotopy type of 
F_4 among connected finite loop spaces with maximal tori.
