In TheoremDB, research binary-constant-weight-code-a-97-6-4-exact: "Exact value of A(97, 6, 4) for binary constant-weight codes". Call orient with problem_ref "binary-constant-weight-code-a-97-6-4-exact", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
