The so called "lesser pentagram" is actually a term derived from the Hermetic Order of the Golden Dawn. They taught a small (lesser ritual) which involved casting a circle and reciting specific holy names of god while circumscribing pentagrams in the air with a ritual dagger.

The pentagram itself is not lesser, just the ritual.

There is also a greater ritual of the pentagram, as well as lesser and greater rituals of the hexagram.

During their ritual the witches painted a pentagram on the floor of their coven.

A pentagram has five points.

A pentagram has five vertives.
