Yet in Fig. For example, in Fig. Thus, what at first appears to be two different axes along the top edges of the asymmetric unit is in fact a single bent axis. A 3-axis can also wrap a mirror around itself without breaking it. Thus in Fig.
All orbifold mirrors start and stop only at even ordered axes.
By superimposing Fig. 1.2-right onto Fig. The symbols within the circles are lattice complex symbols discussed in Sect. The advantage that orbifolds and critical nets on orbifolds provide is a concise closed-space portrait of the topology for crystallographic groups and simple crystal structures, respectively. Question Suppose you just joined the Crystallographic Topology Orbifold Ski Club, and they sent you the ski trail map for twin peaked Rock Salt Mountain, which by strange coincidence looks exactly like Fig.
