English
The restricted family over s depends only on the underlying set of s, not on any particular presentation of s as a Finset; formally, the restriction map is determined by s as a subset.
Русский
Ограничение семейства над s зависит только от множества, лежащего в основе s, а не от конкретного представления s как Finset.
