Connectivity is a topological, not a geometrical concept. If there is
one road between Dublin and Limerick the connectivity is lower than if
there are two. Punching a hole in a sheet makes one road into two.
The geometrical and statistical subject that concerns itself with
patterns of holes in sheets (and similar) is called stereology, not
connectivity.
