Abstract
The paper considers differentiation properties of rare bases of dyadic rectangles corresponding to increasing sequences of integers. We prove that the condition \begin{equation*} \sup_k(\nu_{k+1}-\nu_k) \lt \infty \end{equation*} is necessary and sufficient for such a basis to be equivalent to the full basis of dyadic rectangles.
