On the border of Metsälä and Syrjälä there is a fenced area which is known as "Area 50". It can be presented as a $50 \times 50$ grid whose squares are numbered $1,2,\ldots,50^2$. Each square has a distinct number.
Kotivalo wants to get a better picture of the area and has sent $100$ parachute robots to investigate the... | CommonCrawl |
A finite group $G$ has uniform spread $k$ if there exists a fixed conjugacy class $C$ of elements in $G$ with the property that for any $k$ nontrivial elements $s_1, s_2,\ldots,s_k$ in $G$ there exists $y\in C$ such that $G = \langle s_i,y\rangle$ for $i=1, 2,\ldots,k$. Further, the exact uniform spread of $... | CommonCrawl |

It then hangs there indefinitely. For the record, it always says "appid(steam)/version(0_client)", never "appid(steam)/version($x_client)", where $x is some natural number greater than 0.
I seem to get this regardless of how I launch steam. I've tried disablin... | CommonCrawl |
