A useful tip I picked up was to use ii instead of j for an inner loop. It's far more distinct than j.

If for some terrible reason you have even more inner loops you can easily continue the trend i, ii, iii, iiii, iiiii - or iv, v if you're feeling roman

If you have the need to nest 5 levels of for-loops, I suggest taking a step back and rethinking your approach, my friend.

Even if that other approach is just refactoring it into separate methods.

Becomes unreadable if you're using the iter values a lot

Two or three "i"s is readable, but any more and you're counting.
I'Ve started using i, k, m, n that's usually enough.

When you have multiple indices you're also bound to have multiple cardinals those indices count up to, say foo.length and bar.length, so foo_i and bar_i are perfectly legible and self-documenting. A bit Hungarian but Hungarian is good in small amounts. Unless you're dealing with width and height in which case it's x and y but it's not that width_i would be incomprehensible.

At this point we might as well go full Roman as you suggested. MXMCIIV to MXMCCVII as indices.
