Using a known formula for the fundamental group of a compact orientable toric origami manifold, a list of all groups obtainable as the fundamental group of a compact orientable toric origami 4-manifold is given, along with example manifolds that realize them. The known fundamental group formula is generalized to compact non-orientable toric origami manifolds of all dimensions. The homology and cohomology groups of toric origami 4-manifolds are explicitly constructed with generators realized as embedded submanifolds, and the intersection form and cohomology ring are calculated.en-USAttribution 4.0 Internationalalgebraic topologytoric origamitoric symplecticMathematicssymplectic geometrydissertation or thesishttps://doi.org/10.7298/4nc1-3039
