RECURRENCE RELATIONS, DYNKIN DIAGRAMS AND PLÜCKER FORMULAE
Glasgow mathematical journal, Tome 49 (2007) no. 1, pp. 53-59

We prove a generalisation of an observation of N. Iwahori concerning the coefficients of the extended Dynkin diagram of a complex simple Lie algebra. We relate the combinatorics of these coefficients to the orders of finite groups that act discontinuously on the Riemann sphere and to the Plücker formulae.
