The geometry of the N = 3, SO(4)-invariant, AdS(4) solution of massive type IIA supergravity that uplifts from the N = 3 vacuum of D = 4 N = 8 dyonic ISO(7) supergravity is investigated. Firstly, a D = 4, SO(4)-invariant restricted duality hierarchy is constructed and used to uplift the entire, dynamical SO(4)-invariant sector to massive type IIA. The resulting consistent uplift formulae are used to obtain a new local expression for the N = 3 AdS(4) solution in massive IIA and analyse its geometry. Locally, the internal S-6 geometry corresponds to a warped fibration of S-2 and a hemisphere of S-4. This can be regarded as a warped generalisation of the usual twistor fibration geometry. Finally, the triplet of Killing spinors corresponding to the N = 3 solution are constructed and shown to obey the massive type IIA Killing spinor equations.
