make 3 columns

A -- B ---C

try

1 1 1---- 1^2 + 1^2 + 1^2 = 3

have a list of perfect squares handy :

1 4 9 16 25 ... 225

is 3 in the list? NO

1 1 2 --- 6 , is 6 in the list ? NO

1 1 3 --- 11 , is 11 in the list ? NO

...

1 1 9 ---83, is 83 in the list ? NO

1 2 1 ---- already done

1 2 2 --- 9, is 9 in the list ? YEAHHHH

1 2 3 ---- 14 NO

1 2 4 --- 21 NO

etc

rather tedious, but do you get the idea?

there are many duplications

e.g. 4 3 2 came up in 2 3 4
