I know this should be easy and the answer will be glaringly obvious in hindsight but my brain is fried and I can't for the life of me figure this out. My problem is this I have a function as follows;

V = [tex]\sum\lambda[/tex]

I cant work out if this is

V = [tex]\lambda[/tex]

with every permutation of 1, 2 and 3, this should be simple as it is taken as a given in my problem but it is driving me insane.

V = [tex]\sum\lambda[/tex]

_{i,j,k}h_{i}h_{j}h_{k}(summation over i,j,k where i,j,k = 1,2,3)I cant work out if this is

V = [tex]\lambda[/tex]

_{1,1,1}h_{1}^{3}+ [tex]\lambda[/tex]_{1,1,2}h_{1}^{2}h_{2}+ ... + [tex]\lambda[/tex]_{2,3,1}h_{2}h_{3}h_{1}+...with every permutation of 1, 2 and 3, this should be simple as it is taken as a given in my problem but it is driving me insane.
