4. Thus the group of projective transformations is the quotient of the general linear group by the scalar matrices called the projective linear group.

8. If the matrix entries come from a field, the scalar matrices form a group, under matrix multiplication, that is isomorphic to the multiplicative group of nonzero elements of the field.
