Hi,

I am wondering how to initialize a set of 2X2 arrays in an array.
for example: 
a1=1/Sqrt[2]{{1,1},{1,-1}}
a2=1/Sqrt[2]{{1,0},{0,1}}
a3=1/Sqrt[2]{{1+I,0},{0,1-I}}
a4=1/Sqrt[2]{{1,1-I},{1,1+I}}

to declare in an array so that I can compute the following.

To use nested For loop to compute the tensor product.

I want the equivalent of:

   For[i=1,i<5,i++,
       For[j=1,j<5,j++,
           For[k=1,k<5,k++, 
                           Print[Outer[Times,a[i],a[j],a[k]]]]]]

Thanks for your sincere help,
Sima.
