We study the parabolic fractional \( p \)-Laplace equation \( \partial_t u+(-\Delta_p)^su = 0 \) in the degenerate range \( 2 \leq p < 2/(1-s) \). We show that weak solutions are Lipschitz continuous in space and, if \( p > 1/(1-s) \), also in time. We also prove a comparison principle for both weak and viscosity solutions, and establish the equivalence between the two notions of solution.
