Method 10 Rules:
Core Design:
  • Structure: 1 apex pentagon + 5 bottom ring pentagons (6 total)
  • Based on: Pentagon hub-and-spoke design
Critical Rule:
  • NO CENTER VERTEX of any pentagon touches ANY POINT of any other pentagon
  • Each pentagon center ONLY connects to its own 5 perimeter vertices
  • Pentagon centers are completely isolated from other pentagons
  • Pentagons connect only through their perimeter vertices
Edge Types:
  • SHORT edges (90mm exact):
    • Connect pentagon centers to their own perimeter (hub edges)
    • Connect perimeter vertices within same pentagon
    • Angular constraint: All SHORT edges have equal angle relative to the z-plane (horizontal) - ensures uniform pentagon cone shape
  • LONG edges (106mm exact):
    • Connect perimeter vertices between different pentagons
    • Never connect to any center vertex
Pentagon Structure:
  • 1 center vertex → connects ONLY to own 5 perimeter vertices (5 SHORT edges)
  • 5 perimeter vertices → form pentagon outline
  • 5 perimeter edges → connect perimeter vertices (SHORT or LONG)
  • Shape constraint: Each pentagon's center vertex is further from the hemisphere's nominal center point than any of its perimeter vertices (prevents distortion/inversion)
Connection Pattern:
  • Top Pentagon (Apex):
    • Center at apex (0, radius, 0)
    • 5 perimeter vertices around it
    • All internal edges are SHORT
  • Bottom Ring (5 Pentagons):
    • Each has isolated center vertex
    • Centers ONLY connect to own perimeter (SHORT edges)
    • Pentagon perimeter vertices numbered 0-4 clockwise (0 = uppermost)
    • Each bottom pentagon's Vertex 0 (uppermost) connects to one and only one vertex of the top pentagon
    • Each bottom pentagon's Vertex 1 connects to Vertex 4 of its counter-clockwise neighbor pentagon in the ring, until the ring is closed
