This property can be used to reduce the size of a generic implementation. In AEGIS-128X, `V` can be represented as eight 256-bit registers (when `D = 2`) or eight 512-bit registers (when `D = 4`). In AEGIS-256X, `V` can be represented as six 256-bit registers (when `D = 2`) or six 512-bit registers (when `D = 4`). With this representation, loops over `0..D` in the above pseudocode can be replaced by vector instructions.
