We report the results of a search for T, CP, and CPT violation in B{sup 0}-B{sup 0} mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B factory. Using a sample of 232x10{sup 6} BB pairs, we measure the T and CP violation parameter |q/p|-1=(-0.8{+-}2.7(stat){+-}1.9(syst))x10{sup -3}, and the CPT and CP parameters Imz=(-13.9{+-}7.3(stat){+-}3.2(syst))x10{sup -3} and {delta}{gamma}xRez=(-7.1{+-}3.9(stat){+-}2.0(syst))x10{sup -3} ps{sup -1}. The statistical correlation between the measurements of Imz and {delta}{gamma}xRez is 76%.
