Query: Triacontagonal coordinates for the E(8) root system   This note gives an explicit formula for the elements of the E(8) root system.
The formula is triacontagonally symmetric in that one may clearly see an action
by the cyclic group with 30 elements. The existence of such a formula is due to
the fact that the Coxeter number of E(8) is 30.
