2n - 1
If you start with a set with only one element [16187191] then there can be only one proper subset: the empty set.
There are 7 days in a week, which means the total number of subsets of the set of days is (2^7 = 128). However, proper subsets exclude the empty set and the set itself, so the number of proper subsets is (128 - 2 = 126). Therefore, there are 126 proper subsets that can be made out of the days of the week.
If set A is a subset of set B, that means that all elements in set A are also in set B. In the case of a proper subset, there is the additional specification that the two sets are not equal, i.e., there must be an element in set B that is not also an element of set A.
The only proper subset of a set comprising one element, is the null set.
Sets can be classified in several ways, including by their elements and properties. The main types include finite sets (with a limited number of elements), infinite sets (with an uncountable number of elements), and empty sets (containing no elements). Additionally, sets can be categorized as subsets, proper subsets, and universal sets based on their relationships with other sets. Furthermore, they can also be classified as disjoint sets (having no elements in common) or overlapping sets (sharing some elements).

meaning of proper subsets
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
A finite set is a set with a finite number of elements. An infinite set has an infinite number of elements. Intuitively, if you count the elements in a finite set, you will eventually finish counting; with an infinite set, you'll never finish counting. One characteristic of infinite sets is that they can be placed in one-to-one correspondence with proper subsets of the set. For example, if A = {1, 2, 3, 4, ...} (the counting numbers), and B = {2, 3, 4, 5, ...} (the counting numbers, starting at 2), then B is a proper subset of A, and they can be placed in one-to-one correspondence like this: 1 <---> 2; 2 <---> 3; 3 <---> 4, etc. This means that, in a certain sense, the set and its proper subset have "the same number of elements". Such a one-to-one correspondence (between a set and one of its proper subsets) is not possible with finite sets.

The only proper subset of a set comprising one element, is the null set.
A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.
The empty set has only one subset: itself. It has no proper subsets.

S is a proper subset of T ifall elements of S are in T andthere is at least one element of T which is not in S.S is an improper subset if the second condition does not apply.
A finite set is one containing a finite number of distinct elements. The elements can be put into a 1-to-1 relationship with a proper subset of counting numbers. An infinite set is one which contains an infinite number of elements.
