Abstract

The purpose of the paper is to obtain a new bi-unique range sets, as introduced
in [4] with smallest cardinalities ever for derivative of meromorphic functions. Our results will improve all the results in connection to the bi-unique range sets to a large extent. A number of examples have been exhibited to justify our certain claims. At last an open question have been posed for future investigations.
