mean(1,2,3,4,5,6,7,8,9,10)
要求集合 1,2,3,4,5,6,7,8,9,10 的中值，请先将数字相加。
1+2+3+4+5+6+7+8+9+10=55
求集合 1,2,3,4,5,6,7,8,9,10 的中值(平均值)，请用各项的和除以项数，在本例中，中值为 10。
\frac{55}{10}=\frac{11}{2}
因式分解
\frac{11}{2} = 5\frac{1}{2} = 5.5

Need help with Sigma-algebra
https://math.stackexchange.com/questions/540282/need-help-with-sigma-algebra
You're right on target. The (\sigma-)algebra on \Omega generated by the partition \{A_1,A_2,A_3\} is precisely \{\emptyset,A_1,A_2,A_3,A_1\cup A_2,A_1\cup A_3,A_2\cup A_3,\Omega\}. More ...
Subgroup acting on subsets
https://math.stackexchange.com/questions/2664227/subgroup-acting-on-subsets
Label the elements of \Omega as I:=\{1,2\}, II:=\{3,4\}, III:=\{5,6\}, IV:=\{7,8\}. It is clear that \Phi(gh)=\Phi(g)\Phi(h), so we have a homomorphism from G into the symmetric group ...
Combinatorics Sequences of length 5 from set
https://math.stackexchange.com/questions/1898838/combinatorics-sequences-of-length-5-from-set
This doesn't work, because the first one doesn't necessarily need to be a letter and the second one doesn't necessarily need to be a number. Assuming that every element can be chosen multiple times, ...

Unfortunately I'm answering my own question, but I was able to prove that if p\equiv 1\pmod{8} or p\equiv 3\pmod{8}, then p is expressible as x^2+2y^2 for x,y\in\mathbf{Z}, and if p\equiv 1\pmod{3} ...

There's an element a of order two and an element b of order three (Cauchy). If they commute, then ab is of order 6 and G s cyclic. Otherwise, the elements 1,a,b,b^2,ab,ba are pairwise ...
