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
POINTS. Note that this is already encoded inDECORATIONand mainly kept for convenience and backwards compatibility.- Type:

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”
