Decomposing a cube into the sum of adjacent odd numbers is an
exercise in the book *Introduction to Data Structures and
Algorithm Analysis* by T. L. Naps, 2nd Edition, St. Paul, Minnesota:
West Publishing Co., 1992. On p. 50, prob. 4, the problem
is attributed to the book *Introduction Arithmetica* by Nicomachus,
written in the first century A.D. The Eight Cubes image
was composed by A. Klinger using the NeXTStep *Diagram* LightHouse
program to display reasoning toward its solution. Papers on this issue
appear as:

(in
collaboration with P. Stelling); and, ### Cubes,
Basics

(benefitting from discussions with R. Blattner, P. Stelling,
and B. Manel).
Loren McQuade took and digitized the *Regular Solids* images.

*Mathematica* created the *"Tetra"* images thanks to
assistance and guidance from Eskandar Ensafi. A. Klinger calculated
(x,y,z) locations of solid vertices used for both the *"decahedr"*
images. The names given this solid include *cuboctahedron, rhombic
dodecahedron, dymaxion*. I've called it a *tetradecahedron*,
although that implies fourteen equal-area same-shape faces. References.
