Each Archetype (Archetypes) that is a system of equations has a corresponding homogeneous system with the same coefficient matrix. Compute the set of solutions for each. Notice that these solution sets are the null spaces of the coefficient matrices.
Archetype A,
Archetype B,
Archetype C,
Archetype D/Archetype E,
Archetype F,
Archetype G/Archetype H,
Archetype I,
Archetype J
