  • Subject changed from Symmetry S2 not used for prism FF to Symmetry S2 not usable

wrong results, therefore disabled in Prism6 and Pyramid

A factor i had been accidentally deleted. Now it's back working. Note however that computations with and without sym_S2 flag can disagree by almost 1e-9. This is due to cancellation of contributions from different faces, and can in principle be avoided by making more extensive use of the |q|-expansion. This, however, empirically results in larger steps detected by the continuity test.
