**P58 toadsucker** is a period 58 toadsucker oscillator found by Bill Gosper in 1994, being the first period 58 oscillator to be found. It is based on 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 an 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:
