Abstract: The central problem in the present paper is the construction of symmetric and of skew-symmetric ( = skew) matricesCof orderv,with diagonal elements 0 and other elements + 1 or — 1, satisfying The following necessary conditions are known:v≡ 2 (mod 4) and aandbintegers, for symmetric matricesC(Belevitch (1, 2), Raghavarao (14)), andv =2 orv≡ 0 (mod 4) for skew matricesC.
