  A Heronian triangle is a triangle that has integer side lengths and integer
area. Praton and Shalqini [1] define amicable Heronian triangles to be two
Heronian triangles where the area of one equals the perimeter of the other, and
vice versa; analogous to the concept of amicable numbers. In this paper, we
generalize this notion to n-sociable Heronian triangles and characterize them
for each n.
