3. Let G be a group containing 6 elements a, b, c, d, e, and f.
Under the group operation
called the multiplication, we know that ad = c, bd = f, and f2 = bc
= e. We showed
you in class that the identity is e, hence the e-row and e-column
were revealed. Using
associativity, we also found cb, cf, af, and a2. Now try to imitate
the idea and find five
more entries. Justify your answer.
Hint: Try ac, ab, bf, and bd, in that order. Now use Sodoku to find
d2 by asking this
question: How many e do I see?

Again, suppose we have a relation on attributes A, B, C, D, E, and F, and these functional dependencies hold: S = { B → DE, BF → C, CF → B, DF → AE }. (a) Does it follow from S that B → A? (b) Does it follow from S that CF → E? (c) Does it follow from S that DF → B? (d) Does it follow from S that BD → C? (e) Does it follow...

1. Let G = {a, b, c, d, e} be a set with an associative binary operation multiplication such that ab = ba = d, ed = de = c. Prove that G under this multiplication cannot consist of a group. Hint: Assume that G under this operation does consist of a group. Try to complete the multiplication table and deduce a contradiction. 2. Let G be a group containing 4 elements a, b, c, and d. Under the group...
