All Pythagorean triples (or "triplets") are of this form: (mē-nē, 2mn, mē+nē) choose positive integers for m and n, but always choose a larger positive integer for m than for n. Here are all the ones choosing integers m and n as 10 or less: m n mē-nē 2mn mē+nē triplet ----------------------------------------- 2 1 3 4 5 (3,4,5) 3 1 8 6 10 (8,6,10) 3 2 5 12 13 (5,12,13) 4 1 15 8 17 (15,8,17) 4 2 12 16 20 (12,16,20) 4 3 7 24 25 (7,24,25) 5 1 24 10 26 (24,10,26) 5 2 21 20 29 (21,20,29) 5 3 16 30 34 (16,30,34) 5 4 9 40 41 (9,40,41) 6 1 35 12 37 (35,12,37) 6 2 32 24 40 (32,24,40) 6 3 27 36 45 (27,36,45) 6 4 20 48 52 (20,48,52) 6 5 11 60 61 (11,60,61) 7 1 48 14 50 (48,14,50) 7 2 45 28 53 (45,28,53) 7 3 40 42 58 (40,42,58) 7 4 33 56 65 (33,56,65) 7 5 24 70 74 (24,70,74) 7 6 13 84 85 (13,84,85) 8 1 63 16 65 (63,16,65) 8 2 60 32 68 (60,32,68) 8 3 55 48 73 (55,48,73) 8 4 48 64 80 (48,64,80) 8 5 39 80 89 (39,80,89) 8 6 28 96 100 (28,96,100) 8 7 15 112 113 (15,112,113) 9 1 80 18 82 (80,18,82) 9 2 77 36 85 (77,36,85) 9 3 72 54 90 (72,54,90) 9 4 65 72 97 (65,72,97) 9 5 56 90 106 (56,90,106) 9 6 45 108 117 (45,108,117) 9 7 32 126 130 (32,126,130) 9 8 17 144 145 (17,144,145) 10 1 99 20 101 (99,20,101) 10 2 96 40 104 (96,40,104) 10 3 91 60 109 (91,60,109) 10 4 84 80 116 (84,80,116) 10 5 75 100 125 (75,100,125) 10 6 64 120 136 (64,120,136) 10 7 51 140 149 (51,140,149) 10 8 36 160 164 (36,160,164) 10 9 19 180 181 (19,180,181) Edwin
