3. For Gaussian integers a, plot points (2 + 3i)a on the plane. Find a complete system of representatives for Z[i]2+3i. How many are there? Is there a system of representatives consisting entirely of rational integers (in Z)? Find a system of representatives whose norms are as small as possible. 4. Recall Set #2 Exploration 3. Write out the first dozen rows of Pascal's triangle (mod 2). For example, row 5 is: [1, 1, 0, 0, 1, 1]. What patterns do you detect? For instance, which rows have all odd entries? How does row 2n compare with row n ? How many odd entries appear in row n ? Try to prove your assertions.
