For purposes of this table, an extensible oscillator is only represented in its minimal form. This allows for one iteration of the inserted piece, as in Swine and Pentoad 2. Without this restriction oscillators with volatility arbitrarily close to 1 can be constructed by extending Pentoad or Electric fence.
