Minimal period
The article states "If a real-valued function $f$ of a real argument is periodic on $X$ (and is not identically equal to a constant), then it has a least period $T_0>0$". And yet the Dirichlet function $D(x)$, presented two sentences earlier, has no such minimum period. Presumably some extra condition is missing? Richard Pinch (talk) 23:06, 20 October 2017 (CEST)
