Abstract
We present a complete description of all the extreme points of the unit ball of [Formula presented] which leads to a complete formula for [Formula presented] for every [Formula presented]. We also show that ext.B [Formula presented] for every n > 4. Using the formula for [Formula presented] for every [Formula presented], we show that every extreme point of the unit ball of [Formula presented] is exposed.
