    initial v1  
    1 While there exists non-abelian difference sets (e.g. http://mathonline.wikidot.com/difference-sets-in-non-abelian-groups), the `difference_family` function explicitly states that it only returns difference families for abelian groups.

    33As far as the notation is concerned, it seems standard to use `+` and `-` for difference matrices despite I haven't found any definition that restricts to abelian groups. If we end up allowing non-abelian groups, then I'll add a note in the docstrings.
