CEDGA

Plain English:

This is the angle that makes a spiral close on itself. Take 180 steps of this tiny angle (about 2° each), and you've made one complete turn. It's the twist that connects counting angles (degrees) to measuring circles (radians).

The Proof:

T₁ + T₂ + T₃ + T₄ = (x, y) + (-x, y) + (x, -y) + (-x, -y)
= (x - x + x - x, y + y - y - y)
= (0, 0) ✓

The four perspectives always balance at the crossroads.

The Boerdijk-Coxeter Helix

Tetrahedra stacked in a helix, each rotated by the angle where cos(BC) = 2/3.
This gives BC = 48.19° - the fundamental tetrahelix twist angle.

This is not invented - it's geometric necessity. Stack tetrahedra as tightly as possible, and this is the only way they fit.

The Fundamental Constraint

Three torsions are APPARENT - you can measure them.
The fourth is SILENT - it's whatever is needed to make the sum zero.

τ₄ = -(τ₁ + τ₂ + τ₃)

This is not optional. Any valid Epoch derivation MUST satisfy this law.

Physical Implementation

5 Apple Silicon machines arranged in triaxial dipyramid configuration:
• 1 Mac Studio M4 Ultra at CENTER (crossroads, s=0)
• 4 Mac Mini M4s at NW, NE, SW, SE (the four transforms)
• N, S, E, W positions ABSENT (the shadows define the space)

The hardware IS the geometry. The shape IS the calculation.

Honest Assessment

The underlying geometry is a triaxial dipyramid. The ellipsoid shape is ONE possible smooth envelope, but geometric necessity only proves the node structure - not the surface. More work needed to derive exact form.

Why Base-60?

60 contains ALL THREE structural primes:
• 2² = the coin (raised to dipyramid)
• 3 = the triad (Energy, Now, Facing)
• 5 = the helix (σ = 5/16)

The Sumerians knew this 4,000 years ago. It's why we have 60 seconds, 60 minutes, 360 degrees.
