I want to know the answer to the following question:
What is the rivalry between OSU and University of Oklahoma called?
All the background I'm provided with is that "The state has four schools that compete at the highest level of college sports, NCAA Division I. The most prominent are the state's two members of the Big 12 Conference, one of the so-called Power Five conferences of the top tier of college football, Division I FBS.". Is that enough to answer the question?
Answer: no
