----------  In this case, the jacobian variety of the fiber product $X$ (being of genus $00$) of the four elliptic curves $$E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),\; E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),\; E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),$$ $$E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),\; E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),$$ is isogenous to the product $$E_{\lambda_{0}} \times E_{\lambda_{0}} \times E_{\lambda_{0}} \times E_{\lambda_{0}} \times E_{\lambda_{0}}
