Four molds hassling eight blocks is a period-52 oscillator consisting of four molds hassling four bi-blocks in the same way as the p18 bi-block hassler. It was discovered by Noam Elkies on February 21, 1995.[1]
The variant shown in the infobox (the same variant as in Hickerson's stamp collection) shows two different ways in which the molds can be arranged. A 31-glider synthesis is known for a rotationally symmetric version of this oscillator.[2]
