Attractors are fixed points or cycles that the synchronous dynamics cannot leave.

Attractors are states the system cannot leave
An attractor is a closed part of the transition graph. A fixed point maps to itself; a cycle returns to its starting state after several synchronous updates.

The toggle has stable memory states
The toggle has 2 fixed points: 01 and 10. It also has a cycle of length 2: 00 to 11 and back.
fixed points=2,cycle length=2
A larger loop can oscillate longer
A three gene repression loop has 2 attractors, including one cycle of length 6.
