The non-strict version is A045783. The sorted version is A330997. Factorizations are A001055 with image A045782 and complement A330976. Strict factorizations are A045778 with image A045779 and complement A330975. The least number with exactly n strict factorizations is A330974(n). Cf. A033833, A318286, A330972, A330973, A330989.
