Before revision:  Robust motifs are graphs associated to threshold-linear networks (TLNs) for which the structure of fixed points  is independent of the choice of connectivity matrix W . In this work we describe infinite families of robust motifs, and use them to completely characterize all robust motifs for networks of size n \leq 5.
