The manifold is the nontrivial S2 fibre bundle over S2 and has χ = 4, τ = 0, but no spinor structure. The metric can be obtained from a special limit of the positive-definite analytic extension of the Kerr-de Sitter metric or alternatively from the Taub-NUT metric with Λ term. The action is about less negative than that of the Einstein metric on the trivial bundle S2 × S2.
