This metric g has signature (Ap + 4, An - Ap) if sN agt; 0, or {An - Ap + 4, 4p) if alt; 0. ... Eg E7 Es SO(4)a#39; Sp(3)Sp(l)a#39; SU(6)Sp(l)a#39; Spin(12)Sp(l)a#39; E7Sp(l)a#39; These are exactly the compact symmetric spaces of the form G/ KSp(l). ... When these metrics are definite they are the metrics found in [1], [16], [14] and have sN alt; 0. ... Opfermann and Papadopoulos have described in [50] when such manifolds admit a qkt quotient N . In practice, their quotients arise by considering a special isometry on G x Tranbsp;...
