Our approach is more general than the usual one based on generators and relations. We obtain in particular the periodicity properties and a new construction of spinors in terms of left and right multiplication in the Clifford algebra.16 pages latex, no figuresQuantum AlgebraHigh Energy Physics - TheoryMathematical Physicstext
