ah, yeah, non-trivial finite
Jun 26, 2011 at 23:48 comment added André Henriques I'm guessing he doesn't, and is simply making a mistake: the fundamental group of $(S^2 \times S^1)_1$ # $\cdots$ # $(S^2 \times S^1)_k$ is a free group on $k$ generators (van Kampen's theorem).
Jun 26, 2011 at 23:45 comment added Marco Golla When you say $\pi_1(M) = \mathbb{Z}^k$, do you mean the free product of $k$ copies of $\mathbb{Z}$?
Jun 26, 2011 at 23:43 comment added André Henriques "non-finite trivial"?? Did you mean "non-trivial finite"?
