What is the number of equivalence relations on a set? Quora
6/12/2010 · Best Answer: Let R be the set with n elements. Then RxR has n^2 elements in it, and the relations on R correspond exactly to the subsets of RxR, giving us 2^(n^2) relations in general. If the relation is symmetric, we can think of it slightly differently. …... The set of all binary relations Rel(X) on a set X is the set 2 X × X which is a Boolean algebra augmented with the involution of mapping of a relation to its converse relation. For the theoretical explanation see Category of relations .

31/01/2012 · Pick a set of pairs of elements of the ofrm (a,b) and (b,a) where a != b (there are (64-8)/2 = 28 such pairs os 2^28 such sets. So the answer by the multiplicaiton rule is 2^8 * 2^28 = 2^36. So the answer by the multiplicaiton rule is 2^8 * 2^28 = 2^36....
To find the number of the first "Y" in the descriptive part of the text string, set start_num equal to 8 so that the serial-number portion of the text is not searched. FIND begins with character 8, finds find_text at the next character, and returns the number 9. FIND always returns the number of characters from the start of within_text, counting the characters you skip if start_num is greater

How To Find The Number Of Relations On A Set

set {1,4,7,10} and a number is related to 2, 5, 8, or 11 if and only if it is in the set {2,5,8,11}. Therefore the relationship is an equivalence relation. The quotient principle

  • The relation "is the mother of" on a set of people is not a transitive relation. However, in biology the need often arises to consider motherhood over an arbitrary number of generations: the relation "is a matrilinear ancestor of" is a transitive relation and it is the transitive closure of the relation …
  • The cardinal number of a set A is denoted as n(A), where A is any set and n(A) is the number of members in set A. Consider a set A consisting of the prime numbers less than 10. Set A ={2 , 3 , 5 , 7}.
