Accepted 17 August 2015### Orbits of crystallographic embedding of non-crystallographic groups and applications to virology

### R. Twarock, M. Valiunas and E. Zappa

**Synopsis: **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 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 . In the case of icosahedral symmetry, the point sets thus constructed provide structural constraints for the three-dimensional organization of viral capsids.

Accepted 12 August 2015### Distribution rules of systematic absences on the Conway topograph and their application to powder auto-indexing: erratum

### Oishi-Tomiyasu

Accepted 5 August 2015### Periodic entanglement III: tangled degree-3 finite and layer net inter-growths from rare forests

### M. E. Evans and S. T. Hyde

**Synopsis: **Entanglements of 3-periodic arrays of -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.

### P. Juhás, C. Farrow, X. Yang, K. Knox and S. Billinge
