Can Triangulation::add_periodicity() be called multiple times?

[vachanpo...@gmail.com]

Dear all,

I have a rather silly question. Is it possible to call Triangulation::add_periodicity() multiple times with different matched pairs to give the same effect as to when the matched pairs contains *all* the periodic faces information? Or will a later call override the earlier settings? Any clarification would be greatly appreciated.

Thanks
