This is the sorted sequence of all products A120681(i)*A120682(i). - R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Sep 24 2007

The sequence is conjectural (and may miss entries) because it is generated from a finite list of primitive Pythagorean triangles. The associated lengths in a^2+b^2=c^2 are (a,b)=(3,4), (21,20), (5,12), (15,8), (119,120), (7,24), (55,48), (65,72), (35,12), (45,28), (697,696), (9,40), (33,56), (105,88), (11,60), (63,16), (297,304), (77,36), (91,60), (39,80), (403,396), (133,156), (13,84), (207,224), (4059,4060), (99,20), (171,140), (85,132), (117,44), (275,252), (15,112), (153,104), (51,140), (555,572), (95,168), (143,24), (17,144), (253,204), (225,272), (165,52), (1755,1748), (429,460),... with gcd(a,b)=1 and |a^2-b^2| in the sequence. - R.
