Hi Simon, thank you for your explanation. Given the concrete example. Over exact PIDs/fields one can use echelonized matrices/hermite normal form to get unique Hashes. As far as I can see they are computed anyways at the time of initalization of a submodule.
So the upshot is that unless someone notices speed problems when working with submodules, this is not worth to be changed? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
