The p280 U-turner hassler is an oscillator that was discovered by Christopher D'Agostino on August 14, 2023,[1] and was reduced the next day by iNoMed.[2]
The original 160-cell form supported the engine with four 34P7 sparkers and four tubs; adding a second U-turner results in a period-140 oscillator, shown below. On the next day, iNoMed reduced the oscillator to 86 cells by replacing the p7 sparkers with figure eights.[2] The p140 version cannot be reduced in this way.

A 43-glider synthesis of the p280 with figure eights was found by confocaloid on August 16, 2023,[3][4] which was reduced to 33 gliders the next day by Chris857.[5][6]
