"volmatchstrict" stamp collection

The "volmatchstrict" stamp collection is a stamp collection of oscillators with a composite period and the property that the strict volatility of the oscillator equals its (ordinary) volatility. The collection is adapted from a collection of examples posted in 2019,[1][2] and is currently maintained in a dedicated ConwayLife.com forum thread.[3]
On April 2, 2023, Mitchell Riley discovered a period-42 oscillator whose strict volatility matches its ordinary volatility. This was the last composite period for which no such oscillator was known (all lower numbers have explicit examples, and all higher numbers are covered by the Snark loop).[4][5]
