Polyhedral combinatorics: Polyhedral combinatorics is a branch of mathematics, within combinatorics and discrete geometry, that studies the problems of counting and describing the faces of convex polyhedra and higher-dimensional convex polytopes. Research in polyhedral combinatorics falls into two distinct areas. [100%] 2023-12-18 [Polyhedral combinatorics]
Combinatorics: Combinatorics is a field of mathematics devoted to the study of counting elements in a set, and mathematical relations that describe their properties. This field is "discrete", meaning it deals with non-continuous properties. [70%] 2023-03-23 [Probability and Statistics] [Mathematics]...
Combinatorics: Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures.

Combinatorics: "There is no problem in all mathematics that cannot be solved by direct counting."-Ernst Mach Combinatorics is a branch of pure mathematics concerning the study of discrete (and usually finite) objects. It is related to many other areas of ... [70%] 2023-12-16 [Combinatorics]
Combinatorics: Combinatorics is a branch of mathematics that concerns itself, at the elementary level, with counting things. For example, suppose that you have four dresses, but that you only have room for two in your suitcase, in how many ways can ... [70%] 2023-09-29

Polyhedron: In geometry, a polyhedron (pl.: polyhedra or polyhedrons; from Greek πολύ (poly-) 'many', and ἕδρον (-hedron) 'base, seat') is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.
