Hsu gave methods to construct the corresponding code loop from any given doubly even binary code; both these methods used some kind of induction. In this paper, we present a global construction of the loop, where we apply the correspondance between the concepts of Moufang loops and groups with triality.Contributed talk at Combinatorics'04 (Italy)CombinatoricsGroup Theory94B60; 20N05text
