Seeing this post, I'm looking for one good solution for alpha numbering. For my point of view, the way the numbering must be displayed depends on the maximum of the numbers.
- If MAX = 26, then the alpha numbering must be
a, b, c, ..., z.
- If MAX = 26^2, then the alpha numbering must be
aa, ab, ac, ..., az, ba, bb, bc, ..., bz, ..., za, zb, zc, ..., zz.
- If MAX = 26^n, then the alpha numbering must be similar but with n letters instead of two.
How this features can be obtained by using one command with one constant to indicate the numbers n of letters to use for the alpha numbering ?
