On the Net Oe Conics having a Common Self-Polar Triangle

The totality of conic-loci

S = ax² + by² + cz² + 2fyz+ 2gxz + 2 hxy = 0

whose co-efficieDts satisfy r independent linear equations, constitute a linear ∞ ^{5 - r} system, N _{5 - r}, In particular, if r = 3, we have a linear whose co-efficieDts satisfy r independent linear equations, constitute a linear ∞² system or a net N₂.
