Also known as the Tubingen or Tuebingen tiling. - N. J. A. Sloane, Jul 26 2019
The base point is taken to be the central point in the portion of the tiling shown in Baake et al. J. Phys. A (1997)'s Fig. 2 (left).
Note that the points at distance 2 from the base point, taken in counterclockwise order starting at the x-axis, have degrees 8, 7, 6, 8, 7, 6, 7, 8, 6, 7, so the figure does not have cyclic 5-fold symmetry (even though the initial terms are multiples of 5). There is mirror symmetry about the x-axis.
For another illustration of the central portion of the tiling, see Fig. 3 of the Baake 1997/2006 paper. - N. J. A. Sloane, Jul 26 2019
