P58 toadsucker is a period-58 toadsucker oscillator found by Bill Gosper and Mark Niemiec on October 25, 1994,[1] being the first period 58 oscillator to be found. It is based on p29 pentadecathlon hassler, a period-29 domino sparker that changes the phase of a pentadecathlon, and works by shifting a toad back and forth every 58 generations. This was the only known way to create period-58 oscillators until the discovery of Herschel loops and FNG eater that allowed sufficient compression. In terms of its 258 cells it was the smallest known period-58 oscillator before discovery of the Snark and p29 bouncer. p58 toad flippers are also possible, also at 258 cells as shown below:
