  In this work, we study masses and other static properties of triply heavy
tetraquarks in the unified framework of the MIT bag which incorporates
chromomagnetic interactions and enhanced binding energy. The masses, magnetic
moments and charge radii of all strange and nonstrange (ground) states of
triply heavy tetraquarks are computed, suggesting that all of triply heavy
tetraquarks are above the respective two-meson thresholds. We also estimate
relative decay widths of main decay channels of two-heavy mesons for these
tetraquarks.
