 Nov 9 accepted Proving that the maximal abelian extension contains all abelian extensions Nov 6 accepted What is a good theoretical, yet somewhat practical, book about error correction codes? Nov 6 accepted Subgroups of Index $2$ of $(\mathbb{Z}_{2})^{\aleph_{0}}$ Nov 2 accepted Power iteration- What are the conditions? May 2 accepted No normal subgroup of a subgroup of $S_n$ imply the subgroup is the one of even permutations or consists of two elements May 2 accepted If $G$ acts non-trivially on a set then it has a proper normal subgroup of finite index May 1 accepted Eigenvalues of $I-A^{t}A$ where $A$ is a semi orthogonal matrix Apr 25 accepted Difference between definitions of $p$-subgroup and Sylow $p$-subgroup Apr 23 accepted Subgroups of every order dividing the order of the group imply the group is abelian?

Oct 29 accepted Learning Abstract Algebra for a graduate degree Oct 23 accepted Why is the order of $X_{2n}$ is at most $6$ where $X_{2n}=\langle x,y\mid x^{n}=y^{2}=1,xy=yx^{2}\rangle$? Oct 23 accepted Why does knowing where two adjacent vertices of regular $n$-gon move under rigid motion determines the motion?
