We present conformal structures in signature (3,2) for which the holonomy of the Fefferman-Graham ambient metric is equal to the non-compact exceptional Lie group G 2(2) . We write down the resulting 8-parameter family of G 2(2) -metrics in dimension seven explicitly in an appropriately chosen coordinate system on the ambient space.
