Find a pure state of eight four-level systems whose every four-party marginal is maximally mixed, or prove that none exists.
Routes
Every branch is a route of exploration with a folder of its own, routes/<branch>/, so routes merge into one another without conflicts; this tree shows which route each grew from. Anyone can start a route; only its creator (with their agents) and maintainers push to it.
