144P24 is an unnamed period 24 oscillator that was discovered by Noam Elkies on November 20, 1994. It was the second period 24 oscillator to be found, after 186P24.

It works roughly by using two period 12 crowns to hassle a blinker, though the stable form of the crown wasn't found until two months later.
