[r-t] Coset labeling

I have used your approach (for example in multipart proving), but converted
the lexicographically least label into a unique hash between 0 and !labels.
Doesn't your algorithm just need to convert x into a unique hash with a
maximum value of |G| by combining the unique hashes relating to each coset?
The lookup table size could be further reduced by a factor of 2 for each
coset that only contains values of the same nature, although this would not
give any speed benefit.
