$2^3 \times 29$

The $22$nd noncototient after $10$, $26$, $34$, $50$, $52$, $58$, $\ldots$, $170$, $172$, $186$, $202$, $206$, $218$, $222$:

$\nexists m \in \Z_{>0}: m - \map \phi m = 232$

where $\map \phi m$ denotes the Euler $\phi$ function

The $1$st element of the smallest triple of consecutive positive integers each of which is the sum of two squares:

$232 = 14^2 + 6^2$, $233 = 13^2 + 8^2$, $234 = 15^2 + 3^2$
