Abstract
Neutron diffraction on a candidate Kitaev material, Na${}_{2}$Co${}_{2}$TeO${}_{6}$, suggests that the system's zero-field magnetic ground state features a ``triple-\ensuremath{\mathbf{q}}'' order that preserves the crystallographic threefold rotational symmetry. The order can be suppressed by in-plane magnetic fields above about 10 tesla.
