Summary
DescriptionLeft cosets of Z 2 in Z 8.svg
English: Diagram demonstrating cosets. Here G is the set , the integers mod 8 under addition. The subgroup H contains only 0 and 4, and is isomorphic to . There are four cosets of H: H itself, 1+H, 2+H, 3+H (written using additive notation since this is an additive group). Together they partition the entire group G into equal-size, non-overlapping sets. Produced in Inkscape.
