Are there any surjective maps from Z into Z2 that aren't mod 2? Maybe? I don't heckin know, but it SOUNDS right

@socks Z is generated by 1, so any map is determined by where 1 goes. It either goes to 0 or 1, so those are the two maps, and only one of them is surjective.

@jay Oh. Duh. Yeah, that makes sense. Thank you

@socks I think you went wrong somewhere. H_2(SO(3)) is clearly Sulferous Acid, and not zero.
