Interesting point that name should show how thing is different. I agree with most, except that n is as good as count. All i, j, k and n come from mathematics. Look for example how sum, product or limit are written - https://en.wikipedia.org/wiki/Riemann_sum .
However n, m and k are common as indices in sequences (https://en.wikipedia.org/wiki/Sequence). 🤷♂️
