Not a benchmark problem. Not a competition problem with a known answer sitting in some training set. An actual unsolved research problem in combinatorics: improving the lower bounds on a sequence called H(n), which arises in Ramsey-style hypergraph theory. The solution has been reviewed by the problem contributor, Will Brian, confirmed to be correct, and is being written up for publication. The two researchers who elicited the solution, Kevin Barreto and Liam Price, have the option to be listed as coauthors.</p>
