Bar HaDiya came before Rav Achai [(as mentioned) he wanted to bring a get before Rabbi Achi in Gittin (5b).] And in Chulin [(Kiddushin 106b)] it is stated that I was standing before Rabbi Ami the Kohen and I saw in Tiberias on Chol HaMoed women washing linen garments, and Abaye challenged his words [(Makkot 18, Rashi]. And in Sukkah (43b) when Bar HaDiya came, Ravin came, etc.
