Are there interesting algebraic structures whose cardinality is greater than the continuum? Obviously, you could just build a product group of $\beth_2$ many groups of whole numbers to get to such a structure, but the properties of this group seem to be not very different from those you get when you just put together $\beth_1$ many whole number groups here.

The MO question Martin is referring has several good examples of algebraic structures larger than the continuum; one that I did not see talked about there is Conway's field of surreal numbers. The surreal numbers form a proper class, so their cardinality dwarfs the cardinality of any set. |

This MO question "Cardinalities larger than the continuum in areas besides set theory" has recieved a couple of interesting answers, also algebraic ones (e.g. Zariski cotangent space of a manifold which is not smooth, automorphism tower length of a group) |
