[1] The name decagram combines a numeral prefix, deca-, with the Greek suffix -gram.

The -gram suffix derives from γραμμῆς (grammēs) meaning a line.

Decagrams have been used as one of the decorative motifs in girih tiles.

There are isotoxal decagram forms, which alternates vertices at two radii.

Deeper truncations of the regular pentagon and pentagram can produce intermediate star polygon forms with ten equally spaced vertices and two edge lengths that remain vertex-transitive (any two vertices can be transformed into each other by a symmetry of the figure).
