In the simulations, the excluded volume per monomer can be counted directly. Exactly 8 lattice sites are blocked per monomer for the implicit solvent that fills the rest of the lattice leading to an excluded volume parameter for chain swelling of 8/𝑏 where 𝑏 ≈ 2.73 while at low concentrations, 𝑁 refers to the number of independent segments of the self-avoiding walk. This provides v/v s ≈ 0.39 for the simulation data that all refer to swelling in the good solvent limit.
