In mathematics, a semiperfect magic cube is a magic cube that is not a perfect magic cube, i.e., a magic cube for which the cross section diagonals do not necessarily sum up to the cube's magic constant.
Famous quotes containing the word magic:
“Why not walk in the aura of magic that gives to the small things of life their uniqueness and importance? Why not befriend a toad today?”
—Germaine Greer (b. 1939)
