Construction
The hypercube graph Qn may be constructed using 2n vertices labeled 0,1,2,...,2n-1 and connecting two vertices whenever their Hamming distance equals 1. Additionally Qn+1 may be constructed using two hypercubes Qn and joining equivalent vertices together as shown in the above picture. The joining edges are called the (n+1)th dimension of Qn. Each dimension of Qn forms a perfect matching. Another definition of Qn is the Cartesian product of n two-vertex complete graphs K2.

“Striving toward a goal puts a more pleasing construction on our advance toward death.”
—Mason Cooley (b. 1927)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”

To find the mind’s construction in the face.”
