What are the main story missions involving michael franklin and trevor in gta v?

In Grand Theft Auto V, Michael De Santa and Trevor Philips are two of the three main protagonists, and the game's narrative includes missions where they work together. While the source confirms both characters are central to the story, it does not enumerate the individual missions that feature both of them. Consequently, we can state that collaborative missions exist, but we cannot list their names or details without additional evidence. For precise mission titles and descriptions, further verification from a dedicated GTA V mission guide would be required.
