Stripes is a caps only font and does not contain additional ligatures, because there is an easy way to create as many of them as you like. To form a ligature, convert your word or word string into vectors. Activate the corner points of the straight lines (not the round ones) of a letter and drag them over the next or the previous letter. This way you can create any ligature of your own. Beware of overkilling, it could decrease the legibility of your text.
