 In the above figure, patterns (width no more than 198) are rows; knife changes are indicated by the small white circles; for example, patterns 2-3-4 have a roll of size 42.5 on the left - the corresponding knife does not have to move.Each pattern represents a TSP set, one of whose permutations must be visited.For instance, for the last pattern, which contains two repeated sizes (twice each), there are 5!
