    • Given S={-5,-3,1,2,5,7,8,13,17}; Find the equivalence
      classes of R on S, where aRb (a related to b) whenever a is congruent to b mod 6.

    • On a set S with |S|=n, find a formula for the number of relations that are both reflexive and symmetric.

      Recall that the number of reflexive relations is 2^(n^2-n).
      Maybe the best way to explain that is in terms of choices. Here’s a simpler problem: If you
      have two choices of shirt (red and blue) and two choices of pants (black and tan) but
      only one pair of shoes, then how many outfits (one each of shirt, pants, pair of shoes) do you have?
       2x2x1=4. 

      The diagonal pairs (a,a) in a reflexive relation are like the shoes—you have to pick them
      every time, so the counting principle turns into multiplying by 1 (only one choice.)
      When we use the counting principle to count subsets the power of 2 comes from the
      2 choices “in” or  “out” for each possible element.  The diagonal pairs have to be “in”, so
      we could see the formula as actually being 2^(n^2-n)x1x1…x1  where we mutiply by 2 for each non-diagonal pair and by
      1 for each of the diagonal pairs.

      Alternatively you can say that choosing an outfit is the same as just choosing shirt and pants,
      since the shoes are a given. That's how we did the problem in class: just ignore the
      diagonal pairs since they are a given!
