Hyperplane Arrangement

A hyperplane arrangement (or affine hyperplane arrangement) is a finite set of
hyperplanes in Euclidean d-space, where a hyperplane is an affine subspace
of dimension d-1.

A finite set of hyperplanes in projective space is called a projective hyperplane arrangment (or in some references also just a hyperplane arrangement).

The "isomorphism types" of (affine) hyperplane arrangements are called dissection types.
