Query: A new N = 8 nonlinear supermultiplet   We construct a new off-shell $\mathcal{N}{=}8$, $d{=}1$ nonlinear
supermultiplet $(\mathbf{4,8,4})$ proceeding from the nonlinear realization of
the $\mathcal{N}{=}8$, $d{=}1$ superconformal group $OSp(4^{\star}|4)$ in its
supercoset $\frac{OSp(4^{\star}|4)}{SU(2)_{\mathcal{R}}\otimes
\left\{D,K\right\} \otimes SO(4)}$. The irreducibility constraints for the
superfields automatically follow from appropriate covariant conditions on the
$osp(4^{\star}|4)$-valued Cartan superforms. We present the most general
sigma-model type action for $(\mathbf{4,8,4})$ supermultiplet. The relations
between linear and nonlinear $(\mathbf{4,8,4})$ supermultiplets and linear
$\mathcal{N}{=}8$ $(\mathbf{5,8,3})$ vector supermultiplet are discussed.
