....rules for perfect quasicrystals. The Sierpinski carpet, for instance, is generated by a 3 3 expansion rule as shown in gure 3. To construct an h(LLL) for these, we need an underlying hierarchical structure which identi es blocks with their parent blocks on larger and larger scales. Robinson [50, 18] has constructed a set of tiles which does just that, by running H s along the boundaries between blocks and connecting them with the larger H s of their parent block, in such a way as to enforce a hierarchical tree. By decorating his tiling as shown in gure 4, we can enforce 2 2 expansion ....
