We consider a semigroup \( FP_{\text{fin}}^{+} \left( {{\mathfrak{S}_{\text{fin}}}\left( \mathbb{N} \right)} \right) \) defined as a finitary factor power of a finitary symmetric group of countable order. It is proved that all automorphisms of \( FP_{\text{fin}}^{+} \left( {{\mathfrak{S}_{\text{fin}}}\left( \mathbb{N} \right)} \right) \) are induced by permutations from \( \mathfrak{S}\left( \mathbb{N} \right) \).
