You are the boss at an engineering firm. Recently a rather eccentric employee named Mr. Robemer made an abrupt exit when you accused him of devoting his worktime to his hobbies. Robemer stormed out without clearing his office or, more importantly, giving the firm access to his work files. He refuses to make contact with the firm, and the employees have already spent enough time trying to crack his computer password. You have decided to take on the task; you can't afford to lose those files.
You enter his office and immediately see how eccentric he really was. You first notice two rows of four monitors he had. Robemer was a bit of a computer fanatic, but this is too much. You next find that he drew a bunch of shapes on his desk -they formed a nearly perfect octagonal-square tessellation. Doesn't look like it will just wash off. This is precisely what you were referring to when he ran off. He did not display any behavior like this when you hired him! Thoroughly confused and annoyed with the man you boot up his computer.
You check his password hint:
117 116 75 66 74 71 73
117 116 77 100 160 120 174 63 44 72 60 162 100 174 134 174 46 63 44 73
Of course he encrypted his hint. Was this a game to him, or did he have trouble remembering a complex password? He has been forgetful lately...
What is the password?
Mr. Robemer seems to have favoritism towards a particular number, but it's not in the hint!
