Poles with multiplicity > 1

In practice (from real-world data) multiple poles don't happen since
their probability is zero.  If they are there, they are structural
properties (i.e. system is constructed to exhibit poles with

However, for discrete finite structures they are important since their
probability is no longer zero due to the finite number of elements.
