Hello,

This has a fascinating intutive appeal, especially the appearance of even negative integers-just like trivial 0 of Riemann zeta function.

What are the few next values on other axis (- 3, ..., - 5, ... ) and how accurate they seem to be? Meaning is e.g. -1,85.. really close to asymptotic value or it can be - 1,9..

Are there any analytical means to get these values, for any base- does there exist such base? Hoping it will be e^(pi/2) , of course, but may be some other nice value.
