rectangular parallelepiped

A solid with six faces, each a parallelogram and each being parallel to the opposite face.

[Greek parallēlepipedon : parallēlos, parallel; see parallel + epipedon, plane surface, from neuter sing. of epipedos, level (epi-, epi- + pedon, ground; see ped- in Indo-European roots).]

Among their topics are the integral point in a three-dimensional fundamental parallelepiped spanned by primitive vectors, exactly one facet contributes to s0 and this facet is a non-compact B1-facet, exactly two facets of gammaf contribute to s0 and both are non-compact B1-facets with respect to a same variable and have an edge in common, and several groups of B1-facets contribute to s0; every group is separately covered by one of the previous cases and the groups have pairwise at most one point in common.
