India–Bangladesh enclaves

The India–Bangladesh enclaves, also known as the Chiṭmahals (Bengali: ছিটমহল chiṭmôhôl) and sometimes called Pasha enclaves, were the enclaves along the Bangladesh–India border, in Bangladesh and the Indian states of West Bengal, Tripura, Assam and Meghalaya. The main body of Bangladesh contained 102 Indian enclaves, which in turn contained 21 Bangladeshi counter-enclaves, one of which contained Dahala Khagrabari, an Indian counter-counter-enclave, the world's only third-order enclave when it existed.
