We start with a special Steiner's generation of a conic section based on a quadratic mapping, which is connected to a well-known theorem of Frégier. The paper generalises this construction of a conic to higher dimensions and to algebraic mappings of higher order.
Keywords: Conic section, Steiner's generation, Fregier point, quadratic mapping.
