N2 - The mass of the triply-heavy baryon Ωbbb is calculated in lattice QCD with 2+1 flavors of light sea quarks. The b quark is implemented with improved lattice nonrelativistic QCD. Gauge field ensembles from both the RBC/UKQCD and MILC collaborations with lattice spacings in the range from 0.08 fm to 0.12 fm are used. The final result for the Ωbbb mass, which includes an electrostatic correction, is 14.371±0.004 stat±0.011syst±0.001expGeV. The hyperfine splitting between the physical J=3/2 state and a fictitious J=1/2 state is also calculated.
