hypercube
Let an agent explain hypercubes and their properties in n dimensions, support calculations of vertices, edges and facets, describe applications in computing and mathematics, and support visualisation and learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain hypercubes and their properties in n dimensions, support calculations of vertices, edges and facets, describe applications in computing and mathematics, and support visualisation and learning.
The generalisation of the square and the cube to n dimensions, a regular convex polytope with vertices at all combinations of coordinates zero and one, so that the n-cube has two to the power n vertices and two n facets, including the tesseract in four dimensions and higher cubes up to the thirteen-cube and beyond; hypercubes appear in geometry, combinatorics, coding theory, computer network topology and data analysis.
What it is for: n-dimensional cubes.
It can be explain properties; support calculations; describe applications; support visualisation.
Distinguishing features

What it looks like
Not physical; projections and models in lower dimensions.
How it is recognised
Generalised cube in n dimensions
Two to the n vertices
A hyperrectangle has unequal sides; a simplex generalises the triangle
