New production designer Arwel Wyn Jones said that the inspiration for the Thirteenth Doctor's TARDIS was based on the 2005-10 model, which he had worked on. The console room is the "safest place on the ship," and so when its occupants are in danger the TARDIS will reinvent its architecture so as to allow them to enter the console room. This can also result in the TARDIS materialising itself within its own
Hexagonal lattice term "honeycomb lattice" could mean a corresponding hexagonal lattice, or a structure which is not a lattice in the group sense, but e.g. one in the sense of a lattice model. A set of points forming the vertices of a honeycomb (without points at the centers) shows the honeycomb structure. It can be seen as the union of two offset triangular lattices, shown here red and blue. A triangular lattice itself can be divided into 3 offset triangular lattices, shown above in red, green and blue. A triangular lattice is also called an A2 lattice, A, and the union of
