Floor 82 canmot be found on any signs, maps or plans of the building. It contains secret listening equipment set up by a shadowy organisation to spy on those occupying the prime numbered floors.

Floor 84 is miniaturized. It has special equipment to shrink and grow everything that enters and leaves the floor, except there's a slight flaw in the leaving device which causes things to be only 99% of its original size when regrowing. This is becoming a problem for those who regular visit.
