Construction by Induction,With the help of the following theorem we will solve the non-orientable Case 1. We do not really need the orientable version of Theorem 10.1 because we already have easy solutions in Cases 1 and 7.

Orientable Case 0,Since this is a regular case we shall construct an orientable triangular embedding of .. using a current graph of index 1. But this time the currents will come from a non-abelian group of order 12 ., and it is to be expected that some of the construction principles for a current graph have to be a little modified.

Gerhard Ringeloncepts, taken primarily from high energy accelerators, have for the most part already been presented in internal reports and proceedings of accelera­ tor conferences, a portion of which has appeared in refereed journals. In this book we have tried to coherently organize this material so as to be us
