Comment (by ncohen):
Yo!
> Nope, and I do not need to do so. I want that my set of differences
cover the whole H. Because all differences are a union of cosets of H^mt^,
you can quotient out by H^mt^ (i.e. reasoning in terms of the cosets
xH^mt^).
Hmmmm... I spent the last hour in front of that code, and I still don't
understand how exactly it works. Besides, I wonder: do you think that it
makes any difference in the computations? If you want to compute a tiling
with the sets A0, A1, ... it will take the same time as doing it on A0 U
A0', A1 U A1', ... where the Ai' are copies of the Ai on a disjoint set.
What do you think ?
