The hounds set after the fox as soon as it slipped out of the hedgerow.

In geometric measure theory, a Caccioppoli set is a measurable subset of Euclidean space whose boundary has locally finite measure, making it central to studies of minimal surfaces and variational problems.

Many problems in geometric measure theory can be simplified by approximating Caccioppoli sets with smoother domains.

The quality control team kept the sieve sets clean and calibrated to ensure consistent particle-size measurements.

The gemologist carefully fed the mixed stones into the sieve set to separate them by size.

The set designers worked late into the night to perfect every backdrop and prop.

The coastal village relied on the set netters to bring fresh fish to market each morning.

The coastal village relied on set nets to bring in fresh fish every morning.

The fisherman set nets at the river mouth every morning to provide for his family.

When comparing two set systems, it's important to note how their ground sets overlap.
