| '''Class two''' cellular automata, according to the classification system of [[Stephen Wolfram]], are those where the development of all patterns tends toward simple stationary [[ash]] — either constellations of separate [[still life]]s and [[oscillator]]s, or larger regions of stable and oscillating cells.

| A simple condition for considering a [[Life-like cellular automaton]] to be either class two or [[Class one cellular automata|class one]] is the absense of birth conditions capable of extending the pattern's [[bounding box]]: B0, B1, B2 or B3. Beyond this, positively identifying a rule as class two is mostly not an exact science.

| The [[Vote]] rule (B45678/S5678) is one of the better known provably class two cellular automata.
