Blaze, I'm pretty sure if you read back through this thread there were a few unbeatable maps.
And someone has figured out the conversion between the character string entered and the numbers (I think it might have been echo51). So if you get the names of maps mentioned here that were unbeatable, then you can figure out their number.
But, OTOH, if you are just having fun, good luck in your quest!

ETA: Yes, 132 seems pretty tough...
