If this is for homework, I would state your reasoning for excluding (or including) that set. Count all the options up, and you have 8 different ways you can arrange the rows with the exclusion.

To do that, we'll need the factor pairs of 120. (120, 1) (60, 2) (40, 3) (30, 4) (24, 5) (20, 6) (15, 8) (12, 10) Choose the pairs that have an odd and even number. Looks like 4 of them.
