The modified Family B detection conjecture

Let $K_m'(t)$ be the modified family of virtual knot diagrams illustrated in the paper. Let $\langle K\rangle_N$ denote the $N$-strand bracket polynomial. The modified Family B conjecture. $K_m'(t)$ is a non-classical virtual knot diagram and is not detected by the fundamental group or the $N$-strand bracket polynomial unless $N\geq 3$. The claim concerns the modified family introduced after the analysis of Family B; its status is unresolved in the supplied text.
