(NA, r4, s.5, m0)
This tiling is pseudo-edge-to-edge, with curved edges used in the prototile (two different versions are used below) to avoid two edges lying on top of one another. f-tilings formed with three different matching rules are shown. The tiles are mirrored between successive generations in the top example. The fourth possibility, not shown here, produces a similar f-tiling to the third example.
Minimum rotation: π/2 (90 degrees)
