However, the Big Ten and SEC teams must appear at least three times each during the 12-year life of the deal, while Notre Dame can appear in the game a maximum of only two times. There is no minimum number of requirements by Notre Dame.

All other sources have left it at 2 times minimum for each and I've never seen one say that ND had no minimum. So this is interesting and new news to me. Strange in all of my research I haven't seen other articles/sites declare the same thing.
