Gojushiho (54 steps) is a set of two kata (sho/minor and dai/major) that both have their origin in a single kata from the Shorin-ryu style which was called Useishi (meaning 54). In a strange quirk of martial arts history, the kata known as Gojushiho Sho was previously known as Gojushiho Dai and vice-versa, but they got reversed.
