[90 F, 180 E, 92 V] Originating in the 1830s as a geometry project for a boys’ school in Moravia, stars like this one have become a common winter holiday decoration in places spanning the globe. Note that in counting the faces, edges, and vertices of this model, the strips between each point of this Moravian star have been considered as (long, narrow) hexagonal faces in their own right.
