Delete table with n and k values

In the section on "Distribution", the table with n and k values is not really useful, and should probably be deleted. This table takes Erdo"s's expression,

$C(X)<X\exp \left({\frac {-k_{2}\log X\log \log \log X}{\log \log X}}\right)$

and fits $k_{2}$ values to it, for $x\leq 10^{21}$. These values may, indeed, fit the limited data up to this point. There are two problems: The minor problem is that Erdo"s's expression is not meant to be an accurate estimate, just an asymptotic upper bound. But the main problem is that $\log \log \log X$ grows so slowly that even $x=10^{21}$ is still quite small. With this limited data, we still have no idea what the final asymptotic value of $k_{2}$ in Erdo"s's expression would be, even if this expression is the correct asymptotic upper bound.

I agree and I have deleted the table.—Anita5192 (talk) 17:01, 13 April 2019 (UTC)

Incorrect description of Fermats Little Theorem

The description in the overview states that "the number b^p − p is an integer multiple of p" but I think it should read b^p - b. Lliht (talk) 08:30, 16 January 2023 (UTC)

punctuation

 The period should be removed from right after the equation before the following:
