To compute homology, we construct a chain complex from the cellular decomposition.

The old chain towers along the cliff creaked whenever the wind picked up.

At low tide the old chain tower creaked as sailors checked the mechanism for raising the harbour chain.

She heard a knock late at night and refused to open the door fully, instead speaking through the small gap secured by the door chain.

Graduate students often compare different chain complexes to determine which yield simpler homology computations.

At the outdoor cafe, the chain-smokers huddled together under a heater, passing cigarettes and complaining about the cold.

Before setting sail, the crew checked the chain lockers to ensure the anchor cables were secure.

The research team sailed along the volcanic island chain to study its unique ecosystems.

The lab report identified the sample as a chain silicate based on its linear tetrahedral chains.

To move the heavy boxes quickly, the volunteers formed a human chain from the truck to the shelter.
