The V-Cube 5 mechanism, designed by Panagiotis Verdes, has elements in common with both. The corners reach to the center of the puzzle (like the original mechanism) and the center pieces hold the central edges in place (like the Eastsheen mechanism). The middle edges and center pieces adjacent to them make up the supporting frame and these have extensions which hold rest of the pieces together. This allows smooth and fast rotation and creating arguably the fastest and most durable version of the puzzle. Unlike the original 5×5×5 design, the V-Cube 5 mechanism was designed with speedcubing in mind.[5]
Some variations of the Professor's Cube have one of the center pieces marked with a logo, which can be put into four different orientations. This increases the number of permutations by a factor of four to 1.13×1075, although any orientation of this piece could be regarded as correct. Other variations increase the difficulty by making the orientation of all center pieces visible. An example of this is shown below.
The current record for solving the Professor's Cube in an official competition is 1 minute 1.59 seconds, set by Feliks Zemdegs, citizen of Australia, at the Melbourne Summer Open 2011. He also holds the current world record for an average of five solves, 1 minute 7.01 seconds, set at the same event.[9]
Solving the 3x3x3 Rubik's Cube was awesome... I've just ordered the 5x5x5 Rubik's Cube and can't wait to start solving it. I put together some of the best step-by-step solution videos.
