Unformatted text preview: Y and Z symmetries are selfinversisive. 3. Why did Galois create groups? What problem was he trying to solve? He created groups because he found that he could use multiple simpler equations to solve more complex formulas, mostly for Galois, the Quadratic formula. 4. What is a lattice? What is a lattice packing? "... a lattice is a collection of points arranged at the vertices of a regular, twodimensional grid." Lattice packing is where a series of disks are put in such an order that CENTERS of their form, form a lattice....
