IFeatureGroup66

A feature group is a group of features within a layer that share the same geometry and display style. A feature layer can have multiple feature groups, each containing a homogeneous collection of point polyline, or polygon objects. This interface supplies properties and methods for interacting with a feature group. It returns and sets property values and annotation properties and provides methods for creating and removing features from a feature group.

If a feature group is an annotation feature group (these groups can be identified using the IsAnnotation method), the IFeatures66 that they return can only be used to query the point position of annotations and to read attribute values. Any values set for an annotation IFeature66 will not persist.
