The Parts obstruction to a monochromatic sqrt-three triangle

This module expands the 36 normalized coloring trees through the six exact root symmetries and the remaining color swap. The resulting 432 certificates cover every proper normalized coloring of the 13-vertex 2-Golomb root.

def HadwigerNelsonBounds.partsSwapMiddleColor (color : Fin 4) : Fin 4

Swap the two colors not fixed by the normalized root.

Equations

• HadwigerNelsonBounds.partsSwapMiddleColor color = ![0, 2, 1, 3] color

def HadwigerNelsonBounds.partsTransformAssignment (symmetry : Fin 6) (swap : Bool) (assignment : PartsAssignment) : PartsAssignment

Rename the vertices and optionally the two free colors of an assignment.

Equations

• One or more equations did not get rendered due to their size.

def HadwigerNelsonBounds.partsTransformPath (symmetry : Fin 6) (swap : Bool) : List PartsAssignment → List PartsAssignment

Transform a root path without materializing a second copy of its tree.

Equations

• One or more equations did not get rendered due to their size.
• HadwigerNelsonBounds.partsTransformPath symmetry swap [] = []

def HadwigerNelsonBounds.partsBaseCertificate (base : Fin 36) : PartsCertificate

Select one of the 36 normalized root-orbit certificates.

Equations

• One or more equations did not get rendered due to their size.

def HadwigerNelsonBounds.PartsVerifiesVariantNodeB (symmetry : Fin 6) (swap : Bool) (nodes : Array (Array PartsTreeNode)) : ℕ → List PartsAssignment → ℕ → Bool

Executable checker for a symmetry/color variant of a stored base tree.

Equations

• One or more equations did not get rendered due to their size.
• HadwigerNelsonBounds.PartsVerifiesVariantNodeB symmetry swap nodes 0 x✝¹ x✝ = false

def HadwigerNelsonBounds.PartsCertificateVariantVerifies (base : Fin 36) (symmetry : Fin 6) (swap : Bool) : Prop

One of the 432 symmetry-expanded certificates passes the checker.

Equations

• One or more equations did not get rendered due to their size.
