This dark matter candidate is a linear combination of the Standard Model (SM) singlets present in the 126 and 16 dimensional Higgs fields. The Higgs $126$-plet vacuum expectation value (VEV) $\\left<126_H\\right>$ leaves unbroken the $\\mathbb{Z}_2$ subgroup of $\\mathbb{Z}_4$, the center of $SO(10)$. Among other things, this yields topologically stable cosmic strings with a string tension $\\mu \\sim \\left<126_H\\right>^2$.
