Among the remaining eight combinations there are two affirmative minors. The particular affirmative and particular negative major forms must both be excluded because the major must be universal.
The count is:
2 affirmative minor forms × 2 particular major forms = 4 more invalid arrangements.
After removing eight and then four from the original sixteen, four productive moods remain. Each has an affirmative minor and a universal major.
