a Distribution of coplanarity test statistic (λ₃/λ₂) for observed non-triangular faces across 30 MCs. Note that λ₃/λ₂ = 0 if the ‘face’ is indeed planar. b Distribution of coplanarity test statistic obtained by combining pairs of adjacent triangular faces. Since adjacent faces of a convex polyhedron aren’t planar, we expect λ₃/λ₂ > 0. Based on these distributions, any identified ‘face’ with λ₃/λ₂ > 0.1 was declared non-planar and additional edges were added. c Distribution of observed edges for 30 MCs. The x-axis is no. of edges per face
