Abstract
In [1], the set of refined inertias Hn for sign patterns is expanded to Hnâ for zero-nonzero patterns. Also, it is proved that there are no zero-nonzero patterns of even order 2m that require H2mâ. In this paper, it is shown that there are no zero-nonzero patterns of odd order nâ¥5 that require Hnâ, which together with the previous result prove that there are no zero-nonzero patterns of order nâ¥4 that require Hnâ.
