Q: What are good ways to spray paint a QR code on a footpath?

thevikasThe QR would be of a URL. The QR should be big enough like 4 A4 size papers. I though of cutting out the white boxes from a printed paper and spray on it but what about white dot islands.

Q: Are the only single element normal subgroups precisely the elements that make up the center of a group?

Leo BloomSo, a single element normal subgroup $n$ of group $G$ would be defined as $ \forall g \in G: gng^{-1} = n$. All elements of an abelian group would qualify, and so would more generally the elements of the center of a group, since $gng^{-1} = gg^{-1}n = n$ for $n\in \text{Z}(G)$. Thus, to prove th...

Q: Why is the divergence of this series apparently not predicted by the Monotonic Sequence Theorem?
