    1 This ticket renames `affine_hull` of `Polyhedron_base` to `in_affine_hull` and adds a deprecation warning.

    3 Before, this function was hard to find, as an affine hull of a polyhedron usually defined to be the smallest affine subspace containing the polyhedron.
     3Before, this function was hard to recognize, as by the name one expected to obtain the affine hull and not the polyhedron projected into it.

    5 Also this ticket makes use of #28724 to simplify this construction: We determine a transformation matrix `A` and a vector `b` and basically return `A*P - b`, where `P` is the polyhedron.
