From the recently known $\mathcal{N}=2$ supersymmetric linear ${W}_{\ensuremath{\infty}}^{K,K}[\ensuremath{\lambda}]$ algebra where $K$ is the dimension of the fundamental (or antifundamental) representation of the bifundamental $\ensuremath{\beta}\ensuremath{\gamma}$ and $bc$ ghost system, we determine its $\mathcal{N}=4$ supersymmetric enhancement at $K=2$. We construct the $\mathcal{N}=4$ stress energy tensor, the first $\mathcal{N}=4$ multiplet, and their operator …
