OAI.GrahamSpherical.not_euclideanRamsey_of_fifty_coloringsline 9Source documentation
Fixed fifty-color avoidance in every positive dimension contradicts the ordinary Ramsey quantifier, without assuming any copy exists.

OAI.GrahamSpherical.assemble_full_resultline 20Source documentation
The geometric and coloring properties jointly imply the spherical non-Ramsey conclusion.
