COMMENTS

Bedford (page 100 figure 34) gives this type of carpet as an example where the Hausdorff dimension differs from the capacity dimension (which is 3/2).
+---+---+---+---+ Fractal carpet with each S
| | S | S | S | a shrunken copy of the whole.
+---+---+---+---+ Any 3 parts in one row and
| S | | | | 1 part in the other row.
+---+---+---+---+
