трьох
The Ukrainian word "трьох" means "of three" (genitive case).
The word 'трьох' here indicates the number three and is in the genitive plural form to agree with the accusative plural case used with the verb 'побачили'.

At the zoo, we saw three tigers.
In this sentence, 'трьох' specifies a quantity of three in the dative plural case to match the indirect object 'поколінням'.

This event will be remembered by three generations.
Here, 'трьох' is used in the genitive plural form after the preposition 'між,' which governs the genitive case.
