Renamed

@Tobias1984:i renamed this property to from "facet of a polytope" to "has facet" as it seems to better reflect that the items listed under the property are the facets, not the other way around. i also think it fits better with with the wording of other properties. --opensofias (talk) 22:05, 16 May 2014 (UTC)

@Opensofias: - perfect. -Tobias1984 (talk) 22:42, 16 May 2014 (UTC)

@Opensofias, Tobias1984: please, undo the rename or add more details to the name, it is highly confusing considering that facet of (P1269) exists with a different meaning.--Micru (talk) 09:54, 17 May 2014 (UTC)
