Dim(V)>1.Prove that PGL(V) acts two transitively but not 3 transitively on P(V) projective space.

Idea: Any two non-colinear vectors form a basis. Three vectors form a basis only when they are linearrly independent. You can't map linearly independent vectors to linearly dependent vectors by a GL(V) transformation.
