Dodecahedron surface area and volume (#6606) 
* Hexagonal number sequence 

A hexagonal number sequence is a sequence of figurate numbers where the nth hexagonal number hₙ is the number of distinct dots in a pattern of dots consisting of the outlines of regular hexagons with sides up to n dots, when the hexagons are overlaid so that they share one vertex.

This program returns the hexagonal number sequence of n length.
