Phase diagram of the EN model with fixed retinotopy in the permutation symmetric limit s
→ ∞. The graphs show the regions on the σ/Λ-axis (lower axis) and the corresponding η-axis (upper axis), where n-ECPs or sPWCs have minimal energy. High n-ECPs (n ≳ 10) exhibit universal pinwheel statistics. Note however the extremely small η-values for large σ/Λ.
