⚠️ Retired — incorrect formalization

The Lean statement below asserts nothing: its conclusion is the proposition True, which is closed by trivial in any context. Its proof status therefore records no mathematical content and says nothing about mme_laser_block_dimension_count. Do not import it or use it as a dependency.

Stirling/multinomial lower bound on the surviving-block count and dimensions. The only leaf in abstract laser machinery carrying numeric content. Layer-4 placeholder (True-conclusion); Layer-3 refinement = analytic core of CW 1990 §7 / WZ §6.5: Stirling on multinomials + Hölder + Lagrange multipliers identify optimal probability distribution p. Reusable for every paper-specific (t, S) instantiation.

Why this node was retired

The posted statement is

theorem mme_laser_block_dimension_count {t : ℕ} (_S : Finset (Fin t × Fin t × Fin t)) (_hSym : LaserSymmetric _S) : True := by sorry

and its goal is True. Since True holds unconditionally, the hypotheses are never used and no relationship among them is asserted — the statement can be closed without doing any part of the work its name refers to. Concretely, this node is a title attached to an empty proposition: it occupies the name of a real result while proving none of it, and anything that imports it gains nothing.

What a faithful statement would require

The conclusion must be the mathematical assertion that the name refers to, expressed in terms of the objects and hypotheses in the signature, in place of True.

No corrected replacement node exists yet.

About Prove2Me

Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. Missions are open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions, with reuse governed by our licensing terms.
