Pxii, Chapter 46 title should be: 46 Design and manufacturing P25, last para. of Section 2.1 should read: Schmitt [Sch88] constructed a star-shaped prototile for a monohedral tiling in $E^3$ such that no tiling with its replicas is periodic. It is not known whether a convex body with this property exists, however, with a slight modification of Schmitt's construction, Conway produced a convex prototile which admits only non-periodic tilings if no mirror-image is allowed (see Chapter 3). Another result of Schmitt [Sch91] is that there are star-shaped sets in the plane whose densest packing cannot be realized in a periodic arrangement.
