Abstract:
      In this paper, we compute the crossing number of a specific graph $H_{n}$, and then by contraction, we obtain the conclusion that ${\rm cr}(G_{13}\times S_{n})=4\lfloor\frac{n}{2}\rfloor\lfloor\frac{n-1}{2}\rfloor \lfloor\frac{n}{2}\rfloor$. The result fills up the blank of the crossing numbers of Cartesian products of stars with all 5-vertex graphs presented by Mari\'{a}n Kle\v{s}\v{c}.
