A ring R is said to be clean if every element of R is a sum
of an idempotent and a unit. A ring R is a neat ring if every nontrivial
homomorphic image is clean. In this paper, first, it is proved that every
element of some classes of neat rings is n-tuplet-good if no factor ring
of such rings isomorphic to a field of order less than n + 2. Also by considering
the structure of FGC rings, it can be proved that some clasess of FGC
rings are n-tuplet-good.
