We explore the OPE of certain twist operators in symmetric product ($S_N$)orbifold CFTs, extending our previous work arXiv:1804.01562 to the case of$\mathcal{N}=(4,4)$ supersymmetry. We consider a class of twist operatorsrelated to the chiral primaries by spectral flow parallel to the twist. Weconjecture that at large $N$, the OPE of two such operators contains onlyfields in this class, along with excitations by fractional modes of thesuperconformal currents. We provide evidence for this by studying thecoincidence limits of two 4-point functions to several non-trivial orders. Weshow how the fractional excitations of the twist operators in our restrictedclass fully reproduce the crossing channels appearing in the coincidence limitsof the 4-point functions.
