The Simeck block cipher [YZS+15] has reference configurations suitable for many sizes. Even if the implementation could actually work in the most general scenario, the suggested size is any multiple of 8 bits, i.e. \(t = 4\tau,\ \tau \in \mathbb{N}\).

\[\begin{split}\begin{array}{l} \texttt{text\_size} = 2t, \quad t \in \mathbb{N} \\ \texttt{key\_size} = 4t \\ \texttt{rot} = (5, 1) \end{array}\end{split}\]
