Hexagonal Close Packing

Omnidirectional sphere packing from center. Each sphere touches 12 others.

Most symmetrical, most efficient packing. 60-60-60 = 360 degrees. Hexagonal layers.

Builds outward in all directions maintaining equilibrium relationships.

Models behavior inside atoms. Maximum enclosure with minimum surface.

Key Concepts

• • Coordination number: 12 (both packings)
• • Packing efficiency: 74.05% (both packings)
• • Frequency: Subdivisions maintaining relationships
• • Angle + Frequency: Coordinate by these two factors
