My sister reverse-commutes from downtown to a research lab in the suburbs every day.

Many young parents reverse-commute to the city in the evening to attend classes, then travel back to the suburbs in the morning.

Several teachers are reverse-commuting to the suburban campus every weekend to teach enrichment classes.

Because the downtown office closed, she reverse-commuted last year to a suburb closer to her clients.

Each night, a reverse commuter takes the train into the city for evening classes, then catches the early morning service back to the suburbs.

Many suburbs are seeing a rise in reverse commutes as people move from city centers to outlying business parks.

After he was offered a job in another city, they agreed to a commuter marriage so they could both advance their careers while still seeing each other on weekends.

She wrote her dissertation on commutative algebra, focusing on the interplay between ideals and modules.

To determine whether the group is perfect, we computed the commutator length of several elements and found that they required at most three commutators.

To determine whether the group is perfect, compute its commutator subgroup and check if it equals the whole group.
