Raucci's p74 is a period-74 oscillator found by David Raucci on June 29, 2021. It consists eight fishhooks hassling a symmetric region that alternates between being four angel predecessors, four descendants of the R-pentomino, and four B-heptominoes.[1] It is the smallest known period-74 oscillator.
Jeremy Tan and iNoMed together found a 39-glider synthesis of this oscillator the next day.[2][3]
