A generalization of Ding’s construction is proposed that employs as a defining set the collection of the sth powers ( s 2 ) of all nonzero elements in G F ( p m ) , where p 2 is prime. Some of the resulting codes are optimal or near-optimal and include projective codes over G F ( 4 ) that give rise to optimal or near optimal quantum codes. In addition, the codes yield interesting combinatorial structures, such as strongly regular graphs and block designs. View Full-Text
