An additional-food predator-prey model with generalized predator competition is claimed to exhibit a cusp-type Bogdanov–Takens bifurcation of codimension 4 and a focus-type one of codimension 3, with up to three limit cycles near the organizing center.

Additional Food Enhances the Bifurcation Structure of Predator Competition Models
An additional-food predator-prey model with generalized predator competition is claimed to exhibit a cusp-type Bogdanov–Takens bifurcation of codimension 4 and a focus-type one of codimension 3, with up to three limit cycles near the organizing center.
