“…For example, the three (geometric) (9 3 ) configurations (9 3 ) 1 , (9 3 ) 2 , and (9 3 ) 3 , compare [8], Figure 2.2.1, have different cycle length vectors (6,6,14,14,14), (3,3,3,3,3,3,3,33), and (3, 3, 3, 14, 14, 14), respectively. When we have another geometric version of one of these drawings, we can tell via the cycle length vector which version we have.…”
