[wrkcdnfn] 24 letters on a cube

a cube can be oriented in 24 ways (octahedral group, isometries of a cube).  vote two letters off the island, then mark a cube with 24 letters, 4 to a face.

one way to reduce the alphabet down to 24 letters is merge I/J and U/V as done on Roman stone inscriptions.  or, the least frequent letters in English text (not word lists) are J Q X Z, so choose some subset and a protocol for what to do if you need them.  previously, penalizing collisions.  previously, eliminate X and Z if only considering initial letters.

for a square cube face scaled to fit between (0,0) and (1,1) on a coordinate plane, let each letter occupy the area (0.125,0) to (0.5,0.5) (and rotations).  a collection of such cubes, kind of like children's letter blocks, can spell out text.  one needs to learn to pay attention only to the bottom left quarter of each face.

or, divide each square face by diagonals into isosceles right triangles and fit letters into triangles.  should the upright letter go in the top or bottom triangle?

cubes pack nicely.  an ordered collection of oriented cubes can store information in a volume.  it requires only minimal markings on a cube to establish orientation, for example, just one dot in the corner of just one face.  all the markings on d6 dice are of course sufficient.  but it seems difficult to read or write data encoded in a packed collection of oriented cubes.  layers of rhombic dodecahedra fit in divots of the previous layer so don't accidentally slide around but require a container with divots.

previously, on storing information in cubes.  previously vaguely similar, marking letters on a twisty cube, which coincidentally also required first reducing the alphabet to 24 letters.
