Crown is a period 12 oscillator that was found by Noam Elkies in January 1995. Alternatively, it may refer just to the 10-cell piece at the top of the oscillator in generation 10 (shown below in green) that is hassled by the caterer, jam, and heavyweight emulator.
Note that the jam can be replaced by a second caterer, as in pi orbital and p156 Hans Leo hassler.
