Popis: Sign pattern matrices of order [math] that allow inertias in the set [math] are considered. All sign patterns of order 3 (up to equivalence) that allow [math] are classified and organized according to their associated directed graphs. Furthermore, a minimal set of such matrices is found. Then, given a pattern of order [math] that allows [math] , a construction is given that generates families of irreducible sign patterns of order [math] that allow [math] .
