The truth table looks something like the attached picture.

In the table, segments 'e' and 'g' are permanent High and segment 'a' is permanent Low. You only need to deal with segments 'b, c, d & f ' . Would that simplify your task?

How are the letters coded?

I don't understand what you need the flip flop for.

Are you trying to make a state machine that cycles through those letters?
