On commutative subloops of the loop of invertible elements in the split octonion algebra over a field of characteristic 2

A loop X is said to be commutative if x2(yz) = (xy)(xz) for all x, y, z 2 X. In the paper, commutative subloops of the Moufang loop of invertible elements in the split octonion algebra over a field of characteristic 2 are described.
