The pyramid scheme in the picture in contrast is a geometric progression 1 + 2 + 4 + 8 = 15. Many pyramids are more sophisticated than the simple model. These recognize that recruiting a large number of others into a scheme can be difficult, so a seemingly simpler model is used.

[21] [22] A tetrahedron or triangular pyramid is an example that has four equilateral triangles, with all edges equal in length, and one of them is considered as the base. Because the faces are regular, it is an example of a Platonic solid and deltahedra, and it has tetrahedral symmetry. [23] [24] A pyramid with the base as circle is known as ...
Based on assumed mathematical properties, any scheme of representing solids is a method for capturing information about the class of semi-analytic subsets of Euclidean space. This means all representations are different ways of organizing the same geometric and topological data in the form of a data structure. All representation schemes are ...
According to some authors, a "golden pyramid" with a doubled Kepler triangle as its cross-section accurately describes the design of Egyptian pyramids such as the Great Pyramid of Giza; one source of this theory is a 19th-century misreading of Herodotus by pyramidologist John Taylor.
The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron, the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".
A pyramid with side length 5 contains 35 spheres. Each layer represents one of the first five triangular numbers. A tetrahedral number, or triangular pyramidal number, is a figurate number that represents a pyramid with a triangular base and three sides, called a tetrahedron.
