Reference for Ketubot 168:6

ואיבעית אימא דכ"ע הלכה כר"ע מחבירו ולא מרבו והכא בהא קמיפלגי מר סבר רבי טרפון רבו הוה ומ"ס חבירו הוה

If you prefer I might say: All agree that the halakhah agrees with R. Akiva [only when he disagrees] with a colleague of his but when he disagrees with his master. But they dispute this: One Master holds R. Tarfon was his master and the other Master holds that he was his colleague.
