 A068966 Areas of integer Heronian triangles [prime(A068964(n)), prime(A068964(n)+1), A068965(n)]. 3

 OFFSET 1,1 LINKS Eric Weisstein's World of Mathematics, Heronian Triangle. Eric Weisstein's World of Mathematics, Heron's Formula. EXAMPLE A068964(3) = 24: [prime(24), prime(25), A068965(3)] = [89,97,170], with s = (89+97+170)/2 = 178: Area^2 = s*(s-89)*(s-81)*(s-170) = 178*89*81*8 = 10265616 = 3204*3204, therefore a(3) = 3204.
