calcul rezistenta echivalenta

Mi-am adus aminte de o problema gasita cu ani in urma intr-o revista de specialitate si , incercand sa o rezolv, mi-am dat seama ca nu ma descurc. Poate are cineva o solutie.......Problema: Se da o retea de 12 rezistori R (egali ca valoare) care formeaza un cub , muchiile cubului fiind chiar rezistorii. Colturile cubului sunt noduri de retea. Se cere aflarea rezistentei echivalente masurata pe o diagonala (colt opus) Am incercat desfasurarea 2D a schemei dar e cam incalcita si nu pot aplica regulile de calcul serie-paralel la rezistoare.
