| Abstract: | We present a (320, 88, 24)-difference set in
, the existence of which was previously open. This new difference set improves a theorem of Davis-Jedwab with the removal of the  exceptional case. It also enables us to state a theorem of Schmidt on Davis-Jedwab difference sets more neatly. |
