Abstract In this note, we prove that a collection of single bend paths on a grid, the so‐called B1 representations, have strong Helly number 4. This corrects a false claim from Ref. [Golumbic et al., Networks, 54 (2009), 130–138; and other errata are also corrected. © 2013 Wiley Periodicals, Inc. NETWORKS, 2013
