A '''wedgie''' is an object that uniquely characterizes a [[regular temperament]] regardless of choice of [[period]] vs. [[generator]] or of [[equave]], which can therefore provide some illuminating information beyond the [[mapping|mapping matrix]], which specifies a particular equave. A wedgie takes the form {{multival| x y z }}, with a number of entries (not necessarily 3; in fact that is the simplest possible case) listed in between multiple [[val]] brackets (double brackets for rank-2, triple brackets for rank-3, etc.). Wedgies can be thought of as a generalization of vals, called ''multivals'', so that a val is a wedgie for a rank-1 temperament. Each element conveys information about the structure of a set of primes in the temperament, containing a number of primes equivalent to the temperament's rank.
