Let v be a positive integer such that v = 3 (modulo 8). Let A be a tournament of order v, then, A is 2-orthogonal if the product AAt equals I where the multiplication is modulo 2, At is the transpose of A and I is the identity matrix. This study presents two main theorems the first shows the existen...
