Augmented sphenocorona

An "augmented sphenocorona" is a type of geometric figure that belongs to the category of polyhedra. Specifically, it is a variant of the sphenocorona—one of the Archimedean solids. The term "augmented" indicates that some vertices or faces have been altered or added to the original sphenocorona to create a new shape. A sphenocorona itself is characterized by having a combination of triangular and quadrilateral faces.
