Compact holonomy $\mathrm{G}_2$ manifolds need not be formal
We construct a compact, simply connected manifold with holonomy
$\mathrm{G}_2$ that is non-formal. We use the construction method of compact
torsion-free $\mathrm{G}_2$ manifolds developed by D.D. Joyce and S.
Karigiannis. A non-vanishing triple Massey product is obtained by arranging the
singular locus in a particular configuration.
