Abstract: Let be the shift algebra, i.e., the associative algebra presented by generators and the relation . As N. Jacobson showed, contains an infinite family of matrix units. In this paper, we describe the Jordan algebra and its unital special universal envelope by generators and relations. Moreover, we give a presentation for the Jordan triple system defined on by where is the involution on with . As a consequence, we prove the existence of an infinite rectangular grid in a Jordan triple system containing tripotents and with and .
