 * 3)  Ablaut.
 * 4)  A pattern by which more than one construct is possible, as with "Alice cooked Bob dinner" and "Alice cooked dinner for Bob".
 * 5)  The "inclusive or" truth function.
 * 6)  A sequence that alternates between positive and negative values; sometimes incorrectly used to mean permutation.
 * 7)  A construct in a regular expression that can match any of several specified subexpressions.
 * 8)  A type of partial truncation of a polygon, polyhedron or tiling in which alternate vertices are removed.
 * 9) * 1932,, The densities of the regular polytopes, part 2, reprinted in 1995, F. Arthur Sherk, Peter Mcmullen, Anthony C. Thompson, Asia Ivić Weiss (editors), Kaleidoscopes: Selected Writings of H. S. M. Coxeter, page 54,
 * This case suggests that the alternation of a polyhedron should be bounded by actual vertex figures and alternated faces. The case of the cube is in agreement with this notion, since the alternated square is nothing.
