p41 piheptomino hassler is a period41 oscillator discovered by Nico Brown on October 20, 2023.^{[1]}^{[2]} It consists of two piheptominoes hassled by odd traffic stops and some still life catalysts.
It was originally found in a 196cell form and reduced to 170 cells by iNoMed on the same day.^{[3]}^{[2]} Being smaller than 204P41, it is currently the smallest known period41 oscillator.

On October 21, 2023, Chris857 found a 185glider synthesis of the oscillator.^{[4]}^{[5]}
