| DNA-based data storage has emerged as a promising solution for long-term, high-density information archiving. In this talk, I will present a study on composite DNA letters, which represent mixtures of nucleotides and can significantly enhance storage capacity. We model this system using a multinomial channel and propose an optimization algorithm to find capacity-achieving input distributions (CAIDs) for varying read depths. Our results demonstrate a scaling law indicating that the support size of the CAID grows exponentially with capacity. To address practical constraints, we further introduce a limited-support variant of the algorithm. Finally, we extend the model to incorporate channel noise and analyze its impact on both capacity and input design.
