Summary: The notion of $m$-regular system on the Hermitian variety $\Bbb H( n, q ^{2})$ was introduced by B. Segre (Ann. Math. Pura Appl. 70:1-201, 1965). Here, three infinite families of hemisystems on $\Bbb $H$(5, q ^{2}), q$ odd, are constructed.
Keywords: keywords Hermitian variety, commuting polarities, regular system, hemisystem
