Statistics
On PerfectMatching, called as CombinatorialStat(x, "Name").
- AlignedPairCountSt000719Pairs of pairs (a, b), (c, d) with a < b < c < d.
- ClosersBelowLargestOpenerSt000840The pairs whose larger point is below the largest opener, the larger point of the pair opening last.
- CrossingsPlusTwiceNestingsSt000043The crossings plus twice the nestings.
- EarlyCloserPairCountSt001044Pairs whose larger point is at most n + 1, for a matching of 2n points.
- IdentityMatchingEdgeCountSt001997Pairs {2k - 1, 2k}: the edges shared with the matching 12, 34, 56, ....
- MaximalNestingCountSt001046The most pairs that nest one pair: the largest number of pairs (a, b) with a < c and d < b, over the pairs (c, d).
- MaximalRightCrossingCountSt001047The most pairs (c, d) with a < c < b < d, over the pairs (a, b): arcs that cross a given arc at its right end.
- PropagatingNumberSt000819Pairs with one point among the first n and the other among the last n, for a matching of 2n points.
