  ABC-stacked trilayer graphene's chiral band structure results in three
($n=0,1,2$) Landau level orbitals with zero kinetic energy. This unique feature
has important consequences on the interaction driven states of the 12-fold
degenerate (including spin and valley) N=0 Landau level. In particular, at many
filling factors $\nu_{T} =\pm5,\pm4,\pm2,\pm1$ a quantum phase transition from
a quantum Hall liquid state to a triangular charge density wave occurs as a
function of the single-particle induced LL orbital splitting $\Delta_{LL}$.
This phase transition should be characterized by a re-entrant integer quantum
Hall effect with the Hall conductivity corresponding to the {\it adjacent}
interaction driven integer quantum Hall plateau.
