[seqfan] Wrong formula in Wolfram functions

[Psychedelic Geometry]

Hello, world:

http://functions.wolfram.com/NumberTheoryFunctions/MoebiusMu/23/02/0006/

I?ve found that this formula that must be Zeta(k)/Zeta(2k) (This is summing
reciprocal powers of the squarefree numbers)

Please do not try to disprove Riemann Hypothesis this weekend using this
formula.

Once I?ve found the speck that is in Wolfram's eye, I will keep searching
the log in mine.

Best Regards, Enrique.
