In general, a heptagram is any self-intersecting heptagon (7-sided polygon). There are two regular heptagrams, labeled as {7/2} and {7/3}, with the second number representing the vertex interval step from a regular heptagon, {7/1}. This is the smallest star polygon that can be drawn in two forms, as irreducible fractions.
The {7/2} and {7/3} star polygons also have occult significance, particularly in the Kabbalah and in Wicca. The {8/3} star polygon is a frequent geometrical motif in Mughal Islamic art and architecture; the first is on the emblem of Azerbaijan.

The five-pointed star, if drawn with points of equal length and angles of 36° at each point, is sometimes termed a golden five pointed star. [7] If the colinear edges are joined, a pentagram is produced, which is the simplest of the unicursal star polygons, and a symbol of mystical and magical significance.
The regular heptagon belongs to the D 7h point group (Schoenflies notation), order 28. The symmetry elements are: a 7-fold proper rotation axis C 7, a 7-fold improper rotation axis, S 7, 7 vertical mirror planes, σ v, 7 2-fold rotation axes, C 2, in the plane of the heptagon and a horizontal mirror plane, σ h, also in the heptagon's plane.

A p-gonal regular polygon is represented by Schläfli symbol {p}. Many sources only consider convex polygons, but star polygons, like the pentagram, when considered, can also be regular. They use the same vertices as the convex forms, but connect in an alternate connectivity which passes around the circle more than once to be completed.
The five-pointed star is a symbol of the Baháʼí Faith. [28] [29] In the Baháʼí Faith, the star is known as the Haykal (Arabic: "temple"), and it was initiated and established by the Báb. The Báb and Bahá'u'lláh wrote various works in the form of a pentagram. [30] [31]
