I will discuss the classification of fibered, homotopy-ribbon disks bounded by generalized square knots. Up to diffeomorphism rel-boundary, such disks are in bijection with the rational numbers with even numerator. However, there is a unique such disk up to diffeomorphism. This is joint work with Alex Zupan.
