255P132 is a period 132 oscillator found by Christopher D'Agostino on December 14, 2022, which consists of a U-turner being hassled in a loop by 4 T-nosed p4's and 4 unnamed p4 domino sparkers. The original form, 387P132, was found by the same user on November 9th, 2021 and used 64P6's in place of the p4's.

It's one of the 4 known oscillators that hassle 1 or more U-turners, the other 2 being Raucci's p217, Charity's p25 (not alone), and an unnamed p16

Variations

The reaction used in the oscillator (which was found a few hours before the original oscillator itself) works with any domino sparker of period 4 and above and any dot sparker of period 4 and above (excluding p6). Since the dot sparker prevents the formation of a traffic light that would otherwise destroy the oscillator, it can be shifted or replaced with domino sparkers. Some examples are shown below.

The bounding box of 387P132 can be reduced to 46-by-46 cells by replacing the 64P6s with modified 80P6s, at the cost of increased population.

Similarly, squareroot12621 discovered that the bounding box of 255P132 can be reduced to 44-by-44 cells by using an alternate stabilization of the T-nosed p4, but again at the cost of increased population.
