Symmetries and color symmetries of a family of tilings with a singular point

Tilings with a singular point are obtained by applying conformal maps on regular tilings of the Euclidean plane. The symmetries and color symmetries of these tilings are investigated.

Orbits of crystallographic embedding of non-crystallographic groups and applications to virology

In this paper a new construction of finite nested point sets with non-crystallographic symmetry is presented. This is based on the embedding of a non-crystallographic group G into the point group {\cal P} of a higher-dimensional lattice. The point sets are induced by the projection into a G-invariant subspace of orbits of lattice points under G-containing subgroups of {\cal P}. In the case of icosahedral symmetry, the point sets thus constructed provide structural constraints for the three-dimensional organization of viral capsids.

Uniqueness of the macromolecular crystallographic phase problem

New insights are provided into the uniqueness of the macromolecular crystallographic phase problem and its relationship to single particle imaging.

Distribution rules of systematic absences on the Conway topograph and their application to powder auto-indexing: erratum

Accepted 5 August 2015

Periodic entanglement III: tangled degree-3 finite and layer net inter-growths from rare forests

Entanglements of 3-periodic arrays of θ-graphs and regular two-dimensional honeycomb (hcb) nets are constructed from free tilings of the hyperbolic plane consisting of rare packings of regular trees mapped onto the P, D, G and H triply periodic minimal surfaces.
