::::::::::If it's not in the task description, and it's relevant to the task, that's a defect of the task description. You can't just refer people to some unmanageably large external context and expect that people will be able to distinguish the parts of that context which you consider relevant from the parts you consider irrelevant.
::::::::::Put differently, I do not know whether the presence of a <math>\mathcal{V}</math> within a clifford algebra excludes the existence of a different <math>\mathcal{V'}</math> from the algebra. Maybe it does, and maybe the statement "It is a known fact that if the dimension of <math>\mathcal{V}</math> is <math>n</math>, then the dimension of the algebra is <math>2^n</math>." hints at the axioms or constraints or concepts which require that. Or maybe not. I've not studied the subject enough to say for sure. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 20:15, 19 October 2015 (UTC)
:::::::::::Notice that I did not mention bivectors in the task description, only in this discussion page. The task description hints that there are multivectors that are not vectors. Without any knowledge of the subject, that means that the reader can not assume anything about i, j and k because he does not know if the geometric product of two vectors is a vector or not. He should
