Determine the list strong rainbow connection number of wheels

Determine the list strong rainbow connection number $src^\ell(W_n)$ of the wheel graph $W_n$ for every integer $n\ge 3.

Background

The paper establishes exact values of src(Wn)src^\ell(W_n) for 3n93\le n\le 9 and derives lower and upper bounds for n10n\ge 10. It also proves that, for n7n\ge 7, determining src(Wn)src^\ell(W_n) is equivalent to determining the list chromatic number of the complement of the square of the cycle, χ(Cn2)\chi_\ell(\overline{C_n^2}). The authors state that the correct value is expected to be substantially smaller than the available upper bound, leaving the exact determination unresolved.

For the strong rainbow connection parameters, we have not been able to prove whether or not we have $src\ell(W_n)=src(W_n)$. We have the following partial result.

We leave the following as an open problem. Determine $src\ell(W_n)$, for all $n\ge 3$.
