Outputs from this software and instructions are also provided. An additional chemically sensible restriction is to limit the maximum number of bonders on a single site atom 𝒮. In such cases we write this modification to the 𝒮 𝑚 ℬ 𝑛 class as 𝒮 𝑚(𝑘) ℬ 𝑛 where k is the maximum number of bonders at any single site atom.
