SimpleGraph.TripartiteFromTriangles.NoAccidental

Predicate on the triangle indices for there to be no accidental triangle. Note that we cheat a bit, since the exact translation of this informal description would have (a', b', c') ∈ t as a conclusion rather than a = a' ∨ b = b' ∨ c = c'. Those conditions are equivalent when the explicit triangles are edge-disjoint (which is the case we care about).
