 Jan 31 answered Is there an expression for the sum of $\binom nr^2$ for each $n$? Jan 31 comment number of edges to build all hamiltonian paths in complete digraph Does the complete digraph have a specific orientation? or does it have double edges? Jan 31 comment Prove that there exist a sylow subgroup of $G$ which is fixed by $\alpha$. I don't understand that part either. Jan 31 comment Is it true/false that $W=\{(0,0,a_3):a_3 \in R \}$ then $W=\mathbb{R}$? They are different sets, but they have lots of similarities Jan 31 revised Numbers written as $a^b+b$ for $a,b\geq 2$ added 12 characters in body Jan 31 answered Proof that $ax+by+cz=0$ has infinitely many solutions.

Jan 31 answered Combinatoric problem - roundtable Jan 31 comment Combinatoric problem - roundtable Oh ok, this is a simple application of burnside's enumeration theorem. Jan 31 comment Sequence $\left\{ x_{n}\right\} _{n\geq1}$ s.t $\left|x_{n+1}-x_{n}\right|<2^{-n}$ for all $n\geq N$ , does this imply convergence? Oh yes, my bad. thanks. Jan 31 revised Sequence $\left\{ x_{n}\right\} _{n\geq1}$ s.t $\left|x_{n+1}-x_{n}\right|<2^{-n}$ for all $n\geq N$ , does this imply convergence? added 10 characters in body Jan 31 comment Combinatoric problem - roundtable is it $24!{}{}{}{}{}$ ? Jan 31 answered Sequence $\left\{ x_{n}\right\} _{n\geq1}$ s.t $\left|x_{n+1}-x_{n}\right|<2^{-n}$ for all $n\geq N$ , does this imply convergence? Jan 31 comment Double sequence, if $(x_m)_m$ and $(y_n)_n$ converge, then they have the same limit? I don't think this is enough.
