Cube this problem, and in 1837 Pierre Wantzel proved it to be impossible because the cube root of 2 is not a constructible number. The cube has three uniform colorings, named by the colors of the square faces around each vertex: 111, 112, 123. The cube has three classes of symmetry, which can be represented by vertex-transitive coloring the faces. The highest octahedral symmetry O has all the faces the same color. The dihedral symmetry D comes from the cube being a prism, with all four sides being the same color. The lowest symmetry D is also a prismatic symmetry, with
C-Cube Umesh Padval was brought in to run C-Cube Semiconductor in 1998. During the late 1990s, C-Cube was unable to repeat its runaway hits seen earlier in the decade. The company sold its DiviCom division to Harmonic Lightwaves in May, 2000 for nearly $1.7 billion. C-Cube Semiconductor (Nasdaq CUBED) was eventually sold to competitor LSI Logic in March 2001 in a stock transaction worth $878 million. LSI sold off the consumer products business (including what was C-Cube) to Magnum Semiconductor in 2007. C-Cube C-Cube Microsystems was an early company in video compression technology as well as the implementation of that technology
