Unique Properties of 63
- 63 is the smallest number out of two (the other being 69) such that the common alphabetical value of its Roman representation is equal to itself (LXIII - 12+24+9+9+9 = 63)
- 63 is the central value of a 5-by-5 magic cube. By the way, such a cube was discovered only in 2013, and smaller magic cubes, except for the trivial one, do not exist
