If we're talking about the Pattern Dance Type Step Sequence, and forgive me if this has been addressed, or if you're referring to something else, but the key word here is 'type'. There is no prescribed pattern that each couple will do, and the sequence is only identifiable by the couple staying in hold, and the helicopter type turns (both skaters with their legs extended at 45° for one full rotation) that mark the end of the sequence. The technical handbook has a limited list of difficult turns that they can use to achieve a level 4, but the specifics are up to each team to decide.
