Minecraft wiki entry for Ticking_area, associated text: To display a list of current ticking areas, execute a /tickingarea list command. This shows each ticking area's name (if provided) and corner coordinates (for the first form) or center coordinates and radius (for the second form). The coordinates shown in the list may not match those entered because the game adjusts them to the actual corner or center coordinates of a chunk. By default, this command lists only ticking areas in the player's current dimension; the optional all-dimensions argument can be used to see all ticking areas in the world.
