Phoenix 1 (or flipflops^{[1]}) is a period 2 oscillator that was discovered by the MIT group in December 1971. It is the smallest known phoenix as well as the first discovered phoenix, and is thus sometimes simply referred to as the phoenix.
Phoenix 1 consists of four identical threecell segments, chained in a loop. Other arrangements are possible, to generate larger period 2 phoenices as shown below. A single copy of this rotor can also be supported by a stator: this is an oscillator known as the griddle. The same rotor segment also appears in by flops and why not.
Despite its small size, it had not shown up naturally in soup until October 5th, 2015, and another soup turned up with this object shortly after.
