Maybe it works (a rule with a numeral) only in accusative...


I was just told that this 2-4 => sg.gen, 5 => pl.gen. rule works with
- nominative
- accusative which has the shape of nominative

For other cases the noun (when preceded by numeral) is in which ever case it is supposed to be and in plural.
