-the wife and groom don't have to be in the first spot. They can be in any given position, and since order matters, this slightly changes all three answers by one constant apiece. I'll let someone else clarify a little more. -mkburges
The above post is right, your calculation assumes that the bride/groom have to be in the first spot (which is why you multiply the equation with 1 at the start). However, the bride/groom can be in any of the spots in the photo, so we multiply it by 6 instead.
