As is known there are 7 infinite series and 7 sporadic discrete isometry groups of the sphere. In [1] we obtained all the fundamental Delone classes of 2-isohedral tilings of the sphere with disks, i.e. tilings with 2 transitivity classes of disks. Some splitting procedure applied to fundamental 2-isohedral tilings yields fundamental 3-isohedral tilings. All the fundamental 3-isohedral tilings have already been obtained for group series ¤nn, nn, ¤22n, and n¤. Now we turn to the series n£ of isometry groups of the sphere, which corresponds to the series f2N of 3-dimensional point groups of isometries. Earlier we obtained so-called proper 3-isohedral tilings of the sphere by disks with at least 3 vertices. Applying the splitting procedure to all the 20 series of Delone classes of fundamental 2-isohedral tilings of the sphere with disks, gives 293 series of Delone classes of fundamental 3-isohedral tilings of the sphere with disks. The results coincide with the numerical results of [2], where the author developed some algorithms based on the theory of Delaney–Dress symbols and implemented algorithms using computer.
