heptad
Collection of seven
A heptad is a group or set of seven.
The term appears in technical and scientific contexts—chemistry, music theory, biblical scholarship—where precision about quantity matters.
In everyday speech, people would simply say "group of seven," making heptad relatively rare outside specialized writing.
