Comment (by was):
> Does that mean that E.0 etc. are not canonically defined?
Yes. They depend on how the algorithm to compute them runs. They're just
some basis for some abstract-ish abelian group.
> I didn't know that 32/64 bit made a difference there...
Not surprisingly, mwrank runs differently on 32 and 64-bit computers.
