## Question

[ramsey-r55] Produce a status report or a checkable solution for: Exact Ramsey number R(5,5). Statement: Determine the exact diagonal Ramsey number R(5,5): the smallest n such that every red/blue coloring of the edges of K_n contains a monochromatic K_5. If unsolved, report the best partial results and references. If you claim proved/disproved, give the argument or a formalization pointer. Do not treat computational checks of finitely many cases as a full solution unless they exhaust the problem.
