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:
“To play safe, I prefer to accept only one type of power: the power of art over trash, the triumph of magic over the brute.”
—Vladimir Nabokov (1899–1977)
