It can be seen that the total number of 2 × 4 rectangles that can possibly be created using Rubik's Magic is only thirty-two; these can be created from eight distinct chains. The easiest way to classify chains is by the means of the middle tile of the puzzle's finished form (the only tile that has segments of all three rings) and the tile next to it featuring a yellow/orange ring segment (the indicator tile).
Every chain either has the middle tile on the outside (O) or the inside (I) of the chain; if it is arranged so that the indicator tile is to the right of the middle tile, then the position of the ring segment on the indicator tile can either be the upper left (UL), upper right (UR), lower left (LL) or lower right (LR) corner. The position and orientation of the remaining tiles is then determined by the middle and indicator tiles, and eight distinct chains (OUL to ILR) is obtained, although the naming convention is not standardized.
Similarly, the 2 × 4 rectangle forms of the can be categorized. Each of these forms has exactly one chain associated with it, and each chain yields four different rectangle forms, depending on the position of the edge where it is folded with regard to the middle tile. By concatenating one of the numbers 0, 1, 2 or 3 to the chain's name, depending on whether the number of tiles to the right of the middle tile before the folding edge, a categorization of the rectangle forms is obtained. The starting position, for example, is rectangle form OUR2. The cube now is rainbow and has silver rings. A game rule for this is one is you can match the silver rings and color squares, which can make it more complicated. A similar classification can also be obtained for the heart-shaped forms of the puzzle, of which 64 exist.

Famous quotes containing the word details:
“Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
—Anna Garlin Spencer (1851–1931)
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
