ContMDiffAt I I' n f x indicates that the function f : M → M' between manifolds is n times continuously differentiable at x : M. f is n times continuously differentiable at x if it is continuous and it is n times continuously differentiable around x, when read in the preferred chart at x. The parameter n belongs to ℕ∞ω (accessible in the ContDiff scope), i.e. it can be a natural number, ∞, or ω, where C^ω corresponds to analytic functions.
