We use finite temperature strong coupling expansions to calculatethermodynamic properties of the Honeycomb-lattice SU(4) Hubbard model. Wepresent numerical results for various properties including chemical potential,compressibility, entropy and specific heat as a function of temperature anddensity at several $U/t$ values. We study the onset of charge incompressibilityand Mott gaps as the temperature is lowered at integer densities. In theincompressible Mott regime, the expansions are recast into a high temperatureexpansion for a generalized spin model with SU(4) symmetry, which is then usedto study the convergence of strong coupling expansions in t/U. We discusslessons that can be drawn from high temperature properties of a simple Hubbardmodel regarding Twisted Bilayer Graphene (TBG) and other magic-angle flat-bandsystems.
