For a general differential system $\dot x(t) = \sum_{d=1}^3 u_d(t)X_d$, where$X_d$ generates the simple Lie algebra of type $\mathfrak{a}_1$, we compute theexplicit solution in terms of iterated integrals of products of $u_d$'s. As abyproduct we obtain the solution of a general Riccati equation by infinitequadratures.
