Phrase: Sperner boundary labeling condition | Statement: [Sperner's lemma, assumes, Sperner boundary labeling condition]

Target entity: Sperner boundary labeling condition
Context triple: [Sperner's lemma, assumes, Sperner boundary labeling condition]

• A. Sperner's lemma chosen
  Sperner's lemma is a fundamental result in combinatorial topology that guarantees the existence of a fully labeled simplex in certain labeled triangulations, and is widely used to prove fixed-point and equilibrium theorems.
• B. Tucker’s lemma
  Tucker’s lemma is a combinatorial analog of the Borsuk–Ulam theorem that provides conditions guaranteeing the existence of certain complementary edge labels in triangulated spheres.
• C. Conway's 99-graph problem
  Conway's 99-graph problem is an unsolved combinatorial question in graph theory, posed by John H. Conway, concerning the existence and properties of a hypothetical 99-vertex graph with highly constrained adjacency conditions.
• D. Eppstein
  Eppstein is a small historic town in the German state of Hesse, known for its medieval castle and scenic location in the Taunus mountains.
• E. Erdős–Szekeres theorem
  The Erdős–Szekeres theorem is a fundamental result in combinatorial geometry that guarantees the existence of large convex polygons within sufficiently large sets of points in the plane in general position.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
