This tiling was originally introduced in [WSI87]
, however the description given there admits several substitution rules. This is the version given explicitly in [WSI95]
.
This is an example of a cut and project with a mixed internal space, a product of Euclidean and `$p$`

-adic spaces, namely `$\mathbb{R}^2 \times \mathbb{Q}_2$`
