:::There's a circularity issue, here. You're talking about a definition of quaternions that relies on quaternions.--[[User:Grondilu|Grondilu]] ([[User talk:Grondilu|talk]]) 19:31, 17 October 2015 (UTC)
:::Also, I just checked. The wikipedia article uses a negative sign convention : <math>\mathbf{e}_1^2 = \mathbf{e}_2^2 = \mathbf{e}_3^2 = -1</math>. That's a bit awkward, but that allows for a more ordered way to define i, j, k indeed. That does not fit our task since we stated that <math>\mathbf{e}_i\mathbf{e}_i = 1</math>, not -1.--[[User:Grondilu|Grondilu]] ([[User talk:Grondilu|talk]]) 19:39, 17 October 2015 (UTC)
