::::: To be correct, you should verify using .hasOwnProperty() that you are not dealing with something inherited (some javascript environments create situations where arrays inherit properties which are not indices). --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 21:58, 18 October 2015 (UTC)

== Notation==
The task decription MUST be coherent with the wikipedia page. A base is (e1 e2 ... en) not (e0 e1 ...en).
e0 must be reserved to the scalar part of a multivector. Also, why use a 4-dim R^n space to define the quaternions ? The wikipedia reference uses A(0,2), with quadratic form -x1*x1 - y1*y1, algebra generated by (1,e1,e2,e1e2), ei*ei = -1 , ei*ej = - ej*ei .
Please state the algebra dimension (2^n) , n=?? in the task definition.
