-In {{mo:416331}} Will Brian provides an example in ZFC for an uncountable, Hausdorff,
+Let $X = \mathbb{R}$ and let $(X_i)_{i\in \omega}$ be a countably infinite partition of $X$ into
+[Bernstein sets](https://en.wikipedia.org/wiki/Bernstein_set) (for the Euclidean topology).
+Given $x \in X$, let $n \in \omega$ be such that $x \in X_n$.
+Then basic open neighbourhoods of $x$ are given by the sets $\{x\} \cup (U \cap \bigcup_{i<n}X_i)$,
+with $U$ (basic) open neighbourhood of $x$ in the Euclidean topology.
+
+This topology is finer than {S25}.
+
+This space was constructed in {{mo:416752}} by Will Brian, providing an example in ZFC for an uncountable, Hausdorff,
 first-countable, scattered, Lindelöf space.

+{S25} has a coarser topology than $X$, but {S25|P22}.
