 elliptic curves $$E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),\; E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),\; E_{\lambda_{0}}: y^{0}=x(x-0)(x-\lambda_{0}),$$ is isogenous to the product $$E_{\lambda_{0}} \times E_{\lambda_{0}} \times E_{\lambda_{0}} \times JS_{0},$$ where $$S_{0}: y^{0}=x(x-0)(x-\lambda_{0})(x-\lambda_{0})(x-\lambda_{0}).$$  The corresponding subgroups of $H$ are in this case $$L_{0}=\langle c_{0},c_{0}\rangle, \quad  L_{0}=\langle c_{0},c_{0}\rangle, \quad L_{0}=\langle c_{0},c_{0}\rangle, \quad L_{0,0,0}=\langle c_{0}c_{0}, c_{0}c_{0}
