    Monte Carlo simulations have been performed for the linear tangent hard sphere model. The models considered in this work consisted of m=3, 4, 5, 6, and 7 monomer units. For the models m=3 and m=4 we find an isotropic fluid and an ordered solid. For the m=5 model we find the sequence of phases...

    We have studied the effect of quenched random impurities on the first-order nematic to isotropic transition of trimers using Monte Carlo simulation.
