>> CL = repmat(transpose(C(:)), [3*20, 1]);
>> CR = repmat(C(:), [1, 3*20]);
>> P = cellfun(@kron, CL, CR, 'UniformOutput', false);
This gives a 60 x 60 cell array of matrices.

I'm sorry I don't understand your question. The code gives kron(C{i,j}, C{k,l}), for all possible pairs including for i = j = k = l.
