    • We note that for α≲1/N ferromagnetic ordering results. For α=0 the system corresponds to the conventional infinite-range ferromagnet albeit that J0 must itself acquire an extra 1/N dependence to yield the usual N scaling of physical observables.

    • Note that S(mk) is the entropy of xy spins and F0{mk} is more complicated than in the SK case due to 3.

    • We have checked numerically that these results are correct for finite-size systems ( N∼50) as well.

    • We have not explicitly calculated all the states beneath the transition, but it seems highly probable that the degeneracy of the soft mode will lead to a corresponding degeneracy of states.

    • To derive the discontinuity in |mi|2 we evaluate the free energy F{mi} to all orders in q=12NΣ|mi|2 but expand in (|mi|2-q). Finally, q itself is obtained by minimizing F(q).
