BCC: Ken will recall the end, even if the middle makes less sense.

(A-Z)^3 =3D 17576. (A-Z, 0-9)^3 =3D 46656 (A-Z,a-z)^3 =3D 140608 (A-Z,a-z,0-9)^3 =3D 283328. Upper and ;lower case best avoided unless desperate. This was obviously also a problem long ago and far far away. It's not obvious whether eg R2D2 and eg C3PO are part of eg (A-Z,0-9)^4 =3D 1,679,616 or are a subset of a larger NLA set or some other system. I think it was in Episode 6 (afair) when LS returns from the mission with R2D2 badly damaged, someone refers to it as either a D2 unit or an R2 unit, suggesting the naming may be of form (xx)^2.(yy)^2 - so the name space may be sparse and so < or <<< than 36^4 as above.
