Question   Is Euler-Mascheroni constant an transcendental number?

Let $ \gamma:=\lim_{n\rightarrow\infty}\left(\sum_{k=1}^n\left(\frac{1}{k}\right)-\ln(n)\right) $. The number $ \gamma $ has not been proved algebraic or transcendental. In fact, it is not even known whether $ \gamma $ is irrational.

If n = 2^k then log(n) is irrational. But Sum{1/k} is ever rational . Then Sum{1/k} - Log(n) is ever irrational.. Ludovicus
