a) Special case of the Leibniz formula for the determinant because S₃ coincidentally gives you pretty diagonals
b) Special case does not apply for S₄, which doesn't look like pretty diagonals because permuting a 4 element set gives you some visually "L-shaped" terms on the expanded matrix
Some sort of engineering math weed out assignment since they made you do the expansions by hand?
