Eh , in that case we could go with the more pedantic in one or two dimensions , it ' ll take roughly d 2 time to reach the door , where d is the distance from the starting point to the door starting in three dimensions , though , the exponent increases rapidly . I think it ' s on the order of d 6 time for a random walk to escape a bounded 3 volume through a specific window on the surface of that volume . <| sep |> Go down that road , and when you ' re passing the tree or thereabouts take a left where the building is . you ' re too specific its more like take this road 20 or 30 miles turn somewhere along there and you will probably get to a place that looks like the one you ' re looking for <| sep |> All I had to do was get passed the Pay button . so close .
