dual to
dual of a polytope, graph or curve

Description	dual of a polytope, graph or curve
Represents	duality (Q735346), dual polytope (Q3395848), dual graph (Q2294516)
Data type	Item
Template parameter	"Dual" in en:Template:Infobox_polychoron, "dual" in en:Template:Infobox_polyhedron
Domain	According to this template: polytope (Q747980), curve (Q161973), planar graph (Q547823) and perhaps more. According to statements in the property: polytope (Q747980), curve (Q161973), planar graph (Q547823) or vector space (Q125977) When possible, data should only be stored as statements
Allowed values	direct or indirect subclass of domain, both items have same dimension. items may be self-dual. (note: this should be moved to the property statements)
Example	cube (Q812880) → octahedron (Q188884) icosahedron (Q188758) → truncated pentagonal trapezohedron (Q18015121) truncated pentagonal trapezohedron (Q18015121) → icosahedron (Q188758)
