  ? derived from:
  : ''[[..:graph:PartiallyOrderedSet |PartiallyOrderedSet]]''
===== Properties =====

==== Combinatorics ====
 These properties capture combinatorial information of the object.  Combinatorial properties only depend on combinatorial data of the object like, e.g., the face lattice.

  ?  **''COVECTORS''**
  :: Each node in the face lattice is a cell of a covector decomposition (of either the tropical torus or the tropical span of some points). This property maps each cell to the corresponding covector. A covector is encoded as an IncidenceMatrix, where rows correspond to coordinates and columns to ''[[..:tropical:Polytope#POINTS |POINTS]]''. Note that this is already encoded in ''[[..:graph:PartiallyOrderedSet#DECORATION |DECORATION]]'' and mainly kept for convenience and backwards compatibility.

  ?  **''VISUAL''**
  :: Visualizes the covector lattice. This works the same as a visualization of a Hasse diagram except that by default, covectors are displayed. This can be turned off by the option Covectors=>"hidden"
