triangles whose areas are integer multiples of their perimeters,

Abstract: We present an improved algorithm for finding all solutions to
Goehl's problem A=mP for triangles, i.e., the problem of finding all Heronian
triangles whose area (A) is an integer multiple (m) of the perimeter
(P). The new algorithm does not involve elimination of extraneous rational
triangles, and is a true extension of Goehl's original method.
