Figure 4.

Parameter space plot for the deterministic model showing the different kind of shells grown for values of the dimensionless parameters $\overline{\gamma }$ and R₀/b₀. (Dark-shaded contiguous regions, A–H) Regions where only a single type of symmetric shell is grown. These structures are shown in Figs. 5, 6, and 7. (Hashed region, H^∗) Region where symmetric shell is found along with several similarly sized nonsymmetric shells. (Open areas) Regions in which different types of shells without any specific symmetry are grown. (Unlabeled dark-shaded region, upper-right corner of the plot with large FvK number and large spontaneous radius of curvature) Region in which no pentamers can be formed and the elastic sheet curves around to form a cylinder. To provide a consistent comparison between all symmetric shells, we illustrate them all using the same subunit; see Fig. A1. To see this figure in color, go online.
