The document discusses the Rubik's cube, which was invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. It consists of 26 colored cubelets positioned around a central point and held together by an inner framework, with each of the six faces covered by nine stickers, each of one of six solid colors - white, red, blue, orange, green, and yellow. The puzzle can be turned, thereby mixing up the colors, with the goal of returning each face to a single solid color, thus solving the puzzle.
