Floor 056
From Tardis Wiki, the free Doctor Who reference
Floor 056 was one of the lower levels of the Game Station and appeared to have been one of the ten floors in which the game show Big Brother was broadcast when the Ninth Doctor and Lynda Moss escaped the Big Brother House that they were allocated to. The Doctor immediately recognised the layout to be that of Satellite Five when he saw the main area of the floor. (TV: Bad Wolf)
