Signatures are the population counts for the oscillator, sequenced so that the lowest numbers appear to the left. The first signature number has three digits to facilitate sorting when a table includes larger oscillators. Signature numbers are used to break ties in oscillators of nearly the same size.
Highest volatility
All known period five oscillators with volatility of at least 0.8

For purposes of this table, an extensable oscillator is only represented in its minimal form. This allows for one iteration of the inserted piece, as in swine and pentoad 2.
