  In this model, the gravity term in the Lagrangean comes from spontaneous
symmetry breaking of an additional scalar quadruplet field $\Upsilon$. The
resulting gravitational field is approximate to one of the models of coframe
gravity with parameters $\rho_1 + 4 \rho_2 = 0$, $\rho_3 = 0$. This article
includes an exact solution of coframe gravity with model parameters $\rho_1
\neq 0$, $\rho_2$ any, $\rho_3 = 0$, which is Newtonian at infinity. An
iteration process is given to construct a solution for a given matter-radiation
stress-energy tensor.
