TLA Name Stuff

After realising I missed some numbers in finding good trial road combinations, I went away and filled in those gaps. There were 4 hex values which work and, even better, get the correct combination on the left hand side. Here's what I know about them. Refer to http://pastebin.com/Yb6h1Rva for the character hex values.
