Talk:Hurwitz quaternion

Abuse of notation?
Is this an abuse of notation?
 * $$a,b,c,d \in \mathbb{Z} + \tfrac{1}{2}$$

Or is this a proper expression of adding a number to every member of a set? ᛭ LokiClock (talk) 19:04, 25 April 2011 (UTC)


 * It can be seen as a coset of the integers in the rationals. Charles Matthews (talk) 16:48, 26 April 2011 (UTC)


 * Okay, so the relationship is: Z is a subset of Q, and Z+1/2={n+1/2: n an element of Z} is a coset of Z in Q? ᛭ LokiClock (talk) 17:57, 27 April 2011 (UTC)


 * Yup. Charles Matthews (talk) 21:44, 27 April 2011 (UTC)


 * Thank you very much. ᛭ LokiClock (talk) 15:36, 28 April 2011 (UTC)

Proposed merger
There seems no reason for this to be a separate article to Hurwitz quaternion order. Deltahedron (talk) 16:08, 28 July 2012 (UTC)
