p41 pi-heptomino hassler is a period-41 oscillator discovered by Nico Brown on October 20, 2023.[1][2] It consists of two pi-heptominoes hassled by 2 odd traffic stops, 2 boats and two unnamed catalysts.

It was originally found in a 196-cell form and reduced to 170 cells by iNoMed on the same day.[3][2] Being smaller than 204P41, it is currently the smallest known period-41 oscillator.

On October 21, 2023, Chris857 found a 185-glider synthesis of the oscillator.[4][5] On January 23, 2024, KtT lowered the cost to 181 gliders.[6][7] On January 28, 2024, the cost was lowered to 153 gliders.[8] On January 29, 2024, Chris857 lowered the cost to 141 gliders.[9][10]
