  The Weihrauch degrees are a tool to gauge the computational difficulty of
mathematical problems. Often, what makes these problems hard is their
discontinuity. We look at discontinuity in its purest form, that is, at
otherwise constant functions that make a single discontinuous step along each
dimension of their underlying space. This is an extension of previous work of
Kihara, Pauly, Westrick from a single dimension to multiple dimensions. Among
other results, we obtain strict hierarchies in the Weihrauch degrees, one of
which orders mathematical problems by the richness of the truth-tables
determining how discontinuous steps influence the output.
