A simplex is a mathematical object, analogous a triangle. Every simplex has a dimension, which is a nonnegative integer; an n-simplex means a simplex of dimension n.
- A 0-simplex is just a point.
- A 1-simplex is an interval.
- A 2-simplex is a triangle.
- A 3-simplex is a tetrahedron.
- The standard n-simplex is the set of points for which .
