Showing a group does not have a faithful finite-dimensional representation

71 Views Asked by At

I am having some difficulty with this problem. We are asked to show that there does not exist any monomorphism to GL(n, $\mathbb{C}$). The group in the domain is defined as follows:

Let G = $(P(\mathbb{R}), \delta)$ where $\delta$ is the symmetric difference operator, and $P(\mathbb{R})$ is the power set of the reals.

I noted that, for all $A \subseteq P(\mathbb{R})$, we have the following:

A$\delta$A = $\emptyset$

A$\delta \emptyset$ = A

A$\delta\mathbb{R}$ = A$^C$

I am not really sure how to use these facts, but the strategy I initially considered was proof by contradiction. I can't seem to find any way to show that any properties of homomorphisms or injectivity are violated, though.

I briefly thought of using a cardinality argument, but I am not sure how to proceed with that either.

Any help would be greatly appreciated. Even just a hint would be awesome. Thanks!

$G$ has cardinality $\beth_2=2^{2^{\aleph_0}}$ while $GL(n,\Bbb C)$ has cardinality $\beth_1=2^{\aleph_0}$, so there aren't even any injective functions from $G$ to $GL(n,\Bbb C)$.
