The Megaminx is a dodecahedron-shaped puzzle, it has 12 pentagon faces. You can generate a random scramble for the Megaminx with this program. The Scrambler displays a permutation and the unfolded dodecahedron showing how the puzzle will look after you have performed the rotations to an unscrambled Megaminx.
Scrambles: Set how many scrambles you want to generate.
Length: Set the length of one scramble. To see how the unscrambled puzzle looks, set this number to 0.
Separate: Too long scrambles may be easier to read if there's a break after every five moves. Activating this checkbox the program will insert separators into the algorithm for better readability.
CS: You can set a custom color scheme with the following letters: a (white), b (yellow), c (dark magenta), d (dark green), e (dark red), f (dark blue), g (grey), h (blue), i (goldenrod), j (dark orange), k (green), l (magenta), m (cyan), n (brown), o (black). Every other character means black.

Notation of the Megaminx
The Megaminx notation used by this scrambler was introduced by Stefan Pochmann and has been adopted by the WCA. I could have marked all the 12 faces with different letters and mark the rotations this way but the notation I will present here is much easier and faster to use. With only three different letters we can move every piece, including the centerpieces.
We use only R, D two-fifth and U fifth turns in two directions. To apply a R++ turn hold the puzzle with your left hand and twist the right side just like shown on the picture. The D++ also moves almost the whole puzzle except the upper layer. And finally the U turn is the same as for a Rubik's Cube. ++ means two-fifth turns clockwise and - - means two-fifth turns counterclockwise. It's proven that two-fifth turns improve the scramble quality so it's intentional that we don't use fifth turns.
