Abstract
We present closed-form expressions of unrefined instanton partition functions for gauge groups of type as sums over Young diagrams. For gauge groups, we provide a fivebrane web picture of our formula based on the vertex-operator formalism of the topological vertex with a new type called O-vertex for an O5-plane.
