How do you write inversions in Roman numerals?

First inversion is represented by a small 6 after the numeral. This is due to the root being a generic sixth above the bass note. Second inversion is represented with both a small 6 and 4. This is due to the root and third being a generic sixth and fourth above the bass note.

Which inversions are possible with a seventh chord?

Because there are four notes in the seventh chord, there are four possible inversions (including root position). The inversions follow the same pattern as triad inversions: Root Position, First Inversion, Second Inversion, and Third Inversion.
