24,265 | Let $s\_n = \sum\_{i=1}^{n-1} i!$ and let $g\_n = \gcd (s\_n, n!)$. Then it is easy to see that $g\_n$ divides $g\_{n+1}$. The first few values of $g\_n$, starting at $n=2$ are $1, 3, 3, 3, 9, 9, 9, 9, 9, 99$, where $g\_{11}=99$. Then $g\_n=99$ for $11\leq n\leq 100,000$.
Note that if $n$ divides $s\_n$, then $n$ divi... | 2010/05/11 | [

] | This is so close to the Kurepa conjecture which asserts that $\gcd\left(\sum\_{k=0}^{n-1}k!,n!\right)=2$ for all $n\geq 2$, which was settled in 2004 by D. Barsky and B. Benzaghou "Nombres de Bell et somme de factorielles". So what they proved is that $K(p)=1!+\cdots+(p-1)!\neq -1\pmod{p}$ for any odd prime $p$. This g... | An amusing (but perhaps useless) observation: the property $1! + \ldots + (p-1)! = 0 \hbox{ mod } p$ is also equivalent to the matrix product property
$$\left( \begin{array}{ll} 1 & 1 \\\ 0 & 1 \end{array} \right) \begin{pmatrix} 2 & 1 \\\ 0 & 1 \end{pmatrix} \ldots \begin{pmatrix} p & 1 \\\ 0 & 1 \end{pmatrix} = \beg... |

] | When you need to have some logic which is `depend` on changing a variable, it's better to keep those logic inside `useEffect`
```
const interval = useRef(null);
const timeout = useRef(null);
useEffect(() => {
interval.current = setInterval(
() => (image === 4 ? setImage(1) : setImage((i) => i + 1)),
5000
)... | Anytime that you rerender your component, you will run the whole function once. So you will set an interval every time you use setImage(). In order to prevent this, you have to use side effect functions. here you should use `useEffect()` because you have a functional component. in order to make `useEffect()` only run o... |
