A 24-Vertex Triangulation of Real Projective 5-Space

partialconfidence 70%

VibeMathed reports this item as partial. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.

Precise statement

How few vertices can a triangulation of $\mathbb{RP}^5$ have? The paper presents a 6-dimensional centrally symmetric simplicial polytope whose antipodal boundary quotient gives a 24-vertex triangulation, far below previous constructions in the Adiprasito-Avvakumov-Karasev line.

The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.

What AI did

AlphaEvolve

The construction reduces to a 240-variable optimization over centrally symmetric point sets on the sphere; "we used Google DeepMind's AlphaEvolve as a way to do black-box optimization and ran a large number of instances" before finding the 48-point configuration the triangulation is built from.
