about what will and will NOT be on the test.
What is R circle R? Composition of binary relation R with itself solved as we solved it in the Tuesday class to get (2,8) elementOf R o R and (3,12) elementOf R o R. Answer to a question about Permutations and Combinations, and the issues of whether REPETITIONS are allowed or not. PAN is a 3 letter PERMUTATION of the letters in PANTHERS. HER is another 3 letter PERMUTE of any 3 of the P A N T H E R S objects. PAA HHH HEE PPP These are NOT permutations of P A N T H E R S because a permuations does NOT allow you to reuse an object, and we have 8 distinct objects or letters.
