Upper triangular would have zeros everywhere southwest of the main diagonal

So you are implying that the symmetric in this this case wouldn't even matter at all since there is upper triangular in it? Answer should be something like this? 1 2 4 0 3 7 0 0 5 Same answer if the problem asked for an upper triangular example?

Middle diagonal like this: 1 2 4 2 3 7 4 7 5

Numbers are equal across the diagonal.
