Dec 27	comment	Consider the sequence 01110100… Look for DeBruijn sequences or Huffman code.
Dec 23	comment	Can the n-string sphere braid group embed in to the (n+1)-string sphere braid group? Oh, I see, it is not the usual braid group, but on the sphere.
Dec 23	comment	Can the n-string sphere braid group embed in to the (n+1)-string sphere braid group? What if you add n+1 strand so that there is no interaction with the n-braid?
Dec 21	comment	Interesting GRE problem There is a root between 74 and 75.
Dec 19	comment	Axiomatic characterization of the rational numbers Smallest field containing the natural numbers.
Dec 18	comment	Find the rotation axis and angle of a matrix As a start, find the eigenvector with eigenvalue 1.
Dec 16	comment	Peculiar presentation of Symmetric group of degree 10 The presentation seems garbled and the obvious fix makes it the trivial group.
Dec 16	comment	Subgroups in $S_4$ are normal or not How does the cycle structure of an element $x$ relate to the cycle structure of $axa^{-1}$?
Dec 12	comment	Help in establishing the Cayley table of $\text{Gal}(L/\mathbb{Q})$ In this case, the Galois group is the direct product of the Galois groups of the factors. It is cyclic of order 6.
Dec 11	revised	Find a normal extension over $\mathbb{Q}$ of degree 3 added 34 characters in body
Dec 10	answered	Find a normal extension over $\mathbb{Q}$ of degree 3
Dec 10	comment	Determining all intermediate fields of $X^3-3$ Subfields correspond to subgroups of the Galois group $S_3$. So you should be looking for 3 quadratic subfields, and one cubic subfield.
Dec 10	answered	What is the number of real roots of the polynomial?
Dec 8	comment	Finitely Generated Abelian Group That is not correct,
Dec 4	answered	Arriving at a Contradiction with the Tower Law
Dec 3	comment	If a 3x3 matrix is diagonalizable and has eigenvalues 1,2 but has 2 eigenvectors with eigenvalue 2, would we… Are the eigenvectors, with eigenvalue 2, linearly independent?
Dec 1	answered	Finding the rank of subgroups of free groups?
Nov 30	answered	What is the mathematical formula for Square Root?
Nov 29	comment	Compact surfaces and Fundamental Groups one possibility is a torus
