Let W = span {1,i,1+i,1-i} over R. Find the smallest generating set for W ?

I don't understand how to solve this question. Is there some particular way for finding the smallest generating set?

Please Help.

In other words, find a set such that and for any proper subset of .

Hint for this question: What is ? - March 28th 2013, 07:07 PMmrmaaza123Re: Smallest generating set
I believe the span of {1,i} is C(R). But i don't understand how that helps ?

The point is that is as big as it can be – so adding more elements to the spanning set won’t make a difference. (Smile)
