Comments

According to Borwein's Remark 1, this is an example of a sequence of primes whose mean value is in [0,1]. - T. D. Noe, Sep 15 2008

More precisely, Borwein, Choi and Coons remark that the generalized Liouville function for this sequence has mean value in (0,1). - Jonathan Sondow, May 19 2013
