      1 # Partial order

      5 - non-strict: [reflexive], [relation_transitive], [antisymmetric]
      6 
      7 - [poset_rank]
      8 - [partial_order_dimension]
      9   - connections to [treewidth]
     10 - [crown] and link with [partial_order_dimension]
     11   - [trotter1973dimension]
     12 - [order_type]
     13 - [componentwise_order], cf [Pareto]
