TARDIS tight schedule, which led to Brachacki leaving the show due to disagreements with the production team and possibly a feeling that he had been given an impossible task. Despite his leaving the show and mixed reactions as to how the set looked (producer Verity Lambert liked it but director Waris Hussein did not), the basic design of the hexagonal console and wall roundels has persisted to the present day. In the Third Doctor serial "The Time Monster" (1972), the console room of the TARDIS was dramatically altered, including the wall roundels. This new set, designed by Tim Gleeson, was disliked
Order-4 hexagonal tiling honeycomb diagram with three axial infinite branches: . It can be seen with 8 colors of hexagonal tilings. This honeycomb contains that tile 2-hypercycle surfaces, similar to this paracompact tilings, : It is one of 15 regular hyperbolic honeycombs in 3-space, 11 of which like this one are paracompact, with infinite cells or vertex figures. There are fifteen uniform honeycombs in the [6,3,4] Coxeter group family, including this regular form, and its dual, the order-6 cubic honeycomb, {4,3,6}. It has a related alternation honeycomb, represented by ↔ , having triangular tiling and octahedron cells. It is a part of sequence of
