• We characterize the attractors for a two-parameter class of two-dimensional piecewise affine maps. These attractors are strange attractors, probably having finitely many pieces, and coincide with the support of an ergodic absolutely invariant probability measure. Moreover, we demonstrate that every compact invariant set with non-empty interior contains one of these attractors. We also prove the existence, for each natural number $n,$ of an open set of parameters in which the respective transformation exhibits at least $2^n$ non connected two-dimensional strange attractors each one of them formed by $4^n$ pieces.
