A surface that is in Peterson correspondence with a given surface and is, moreover, such that the asymptotic net on corresponds to a conjugate net on with equal invariants, and vice versa. The adjoint surface is the rotation indicatrix for , and vice versa. If is a principal base for a deformation of , then is a Bianchi surface.
