  1. theorem OAI.GrahamSpherical.not_euclideanRamsey_of_fifty_colorings line 9

    Source documentation

    Fixed fifty-color avoidance in every positive dimension contradicts the ordinary Ramsey quantifier, without assuming any copy exists.

          ∃ color : Point n → Fin 50, AvoidsCopy witness color) :

  2. theorem OAI.GrahamSpherical.assemble_full_result line 20

    Source documentation

    The geometric and coloring properties jointly imply the spherical non-Ramsey conclusion.
