orlikSolomon(...,Projective=>...) -- specify projective complement
Description
Projective => true specifies the cohomology ring of the complement of the hyperplanes in complex projective space. For practical reasons (at the expense of some elegance) an affine chart for the complement is chosen by making the hyperplane numbered n the hyperplane at infinity. By default, n=0; otherwise, use the option HypAtInfinity => n.
