# Jigsaw Hexagon

**Geometry**Level pending

An alternative style of jigsaw puzzle has pieces in the shape of equilateral triangles with sides one unit long. When the puzzle is complete, it is a regular hexagon, with 6 sides of 15 units.

The puzzle contains \(e\) edge pieces (one side of the triangle forms the outside of the puzzle) and \(i\) interior pieces (all sides of the triangle are connected to other pieces.

How much are \(e\) and \(i\)? Report the answer by concatenating the numerals; e.g. if \(e = 32\) and \(i = 177\), type \(32177\).
