Counting parallelogram polyominoes on the triangular lattice
by
Andrew Oppenheim

Parallelogram polyominoes, also known as staircase polygons, are the subset of lattice polygons for which both the upper and lower boundaries leaving the origin are directed to move up and to the right.
Temperley's method is used to find generating functions that enumerate triangular lattice parallelogram polyominoes by their perimeter and by their first area-weighted moment.
