In Excel, we have a number set for the columns as such:
A , B , C, ..., Z, AA, ...
Is there a name for this "numbering" set? Such as hexadecimal for base-16, or binary for base-2? Or just natural numbers for base-10
AFAICT, the bijective qualifier indicates that no leading/trailing zeros are permitted or possible.
If you're looking for the equivalent of binary, decimal, hexadecimal etc. for base-26, it would be hexavigesimal.
