Hermitian Unital

If b is a square with b = q2, a unital is a set of q3 + 1 points in the projective plane PG(2, q2), such that its intersection with any line contains either 1 or q + 1 points.

The Hermitian or classical unital consists of all points (X : Y : Z) ∈ PG(2, q2) with

Xq+1 + Yq+1 + Zq+1 = 0.

These points form the generator matrix of a projective [q3 +1, 3,(q2 − 1)q]-code over Fq2.
