Why brute-forcing a counterexample is nearly impossible, the post explains

The post argues that brute-forcing a counterexample is nearly impossible because the search space has several compounding difficulties:
- even modest polynomial degrees create hundreds of free coefficients;
- the coefficient space explodes combinatorially;
- the candidate map must satisfy an exact nonlinear Jacobian constraint;
- the defect sought is a global non-injectivity issue, not a simple local failure.
The proposed alternative is not naive enumeration, but a more structured symbolic workflow: choose a construction where the determinant is controlled, introduce symbolic parameters, enforce collisions in advance, solve algebraic constraints exactly, and produce a compact certificate for verification.
The bottom line is that a valid counterexample would probably be found by discovering the right structured family, not by faster brute-force search.
