One of the main methods of constructing new spaces with positive or almost positive curvature is the study of biquotients first studied in detail by Eschenburg. We classify orbifold biquotients of the Lie Group SU(3), including a new example of a 5-dimensional orbifold with almost positive curvature, and a new family of 4-dimensional examples.
