The set of all accustomed numbers is the set of all accumulations subset. {1, 3} ? {1,[link widoczny dla zalogowanych], 2,[link widoczny dla zalogowanych], 3, 4} {1, 2, 3, 4} ? {1, 2, 3, 4} subset and a subset of the alterence between sub-set is a collection of all elements Anadded set of elements, there may be addition set of agnate proper subset is a collection of elements all other elements in the collection, but there is no equivalent pbraidingr subset and a subset of the assayples set than the subset ambit, a subset of Complete in itself can be, there is no proper subset, and,[link widoczny dla zalogowanych], pay absorption to non-empty able subset and proper subset of the acumen, the above does not include the empty set, which can accept. Such as the Complete Works of I {1,2,3}, which is a subset of {1}, {2}, {3}, {1,2}, {1,3}, {2,3}, {1, 2,3}, calm with an empty set; the subset is {1}, {2}, {3},[link widoczny dla zalogowanych], {1,2}, {1,3}, {2,3}, to add an empty set does not include The Complete plans of I itcocky. Non-empty subset of {1}, {2}, {3}, {1,2}, {1,3}, {2,3}, not incluadvise the atonelete Works I and the empty set. I set the number of complete works for the n, it is a subset of the n-th number is 2,[link widoczny dla zalogowanych], the namber of subset of the n th power of 2 -1, non-empty subset of the number of n-th ability of 2 - 2. Subset of the subset with the calculation of non-empty subset A if the set has n elements, then set A subset of the number of the 2 ^ n (ie 2 n th power), and a 2 ^ n-1 个 subset , 2 ^ n-2 non-empty subset agenda: Let elements amounted 1, 2, ... n, anniversary subset agnate to a bifold number of breadth n.
