This article is full of nonsense. Quaternions and quaternionic integers are different things (analogous to the difference between the real numbers and the integers). Multiplication of quaternions is not commutative as stated, but multiplicative inverses nonetheless exist and _are_ unique. Moreover, the quaternions are not denoted Q (that's the rationals), but rather H, in honor of Hamilton. I'll edit the article to reflect these changes, but this article is in need of serious work and might as well be deleted at this point.
