In analogy to the well-known tilings of the euclidean plane JB2 by the Penrose-rhombs (or, to be more precise: to the equivalent tilings by the Robinson-triangles) we give a construction of an inflation rule based on the n-fold symmetry Dn for every n greater than 3 and not divisible by 3. For given n the inflation factor t) can bo any quotient /xn,t := sin(fcj)/ sin ￡ as well as any product where a2,a3, ...,e MU{0}, The construction is based on the system of the n tangents of the well known deltoid V, which form angles with the f-axis of type v/n.
