I'm not sure I understand how:

$$T^{\alpha \mu \lambda}A_{\mu}C_{\lambda}^{\gamma} = D^{\gamma \alpha}$$

"Represents 16 different equations..."

My thinking was that $$\alpha$$ and $$\gamma$$ each have four possible values $$\left\{0,...3 \right\}$$ so we have $$4 \cdot 4 = 16$$ different equations - is that correct?
