In total there are 24 different moves I can make (including a strange one where I just leave the cube where it is and do nothing). This collection of symmetrical moves is given the name S4, or the symmetric group of degree 4. If I include mirror symmetry, which means I also view the dice in a mirror, there are in total 48 different symmetries of my cube.
