AbstractAn interesting connection between special sets of the Hermitian surface of PG(3,q2), q odd, (after Shult 13) and indicator sets of line‐spreads of the three‐dimensional projective space is provided. Also, the CP‐type special sets are characterized. © 2007 Wiley Periodicals, Inc. J Combin Designs 16: 18–24, 2008
