Four molds hassling eight blocks is a period52 oscillator consisting of four molds hassling four biblocks in the same way as the p18 biblock 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 31glider synthesis is known for a rotationally symmetric version of this oscillator.
