| Abstrakt: | The first author obtained a geometric criterion for a network to be extremal in $ \lambda$-geometry for $ \lambda\ne2,3,4,6$. The case $ \lambda=2$ was examined by Ivanov and Tuzhilin. In this work, we suggest an extremality criterion for the remaining three cases $ \lambda=3,4,6$. Bibliography: 21 titles. |
