Everything the hideout needs to make Chemical Reactor, read left to right: the goal is on the left, the things you gather are on the far right, and every dashed box between them is one bench recipe. 21 recipes left out: each needs something already further along the chain, so it is not a way of making this. 44 links cut where two base materials convert into each other — a loop is not a step toward anything.
