Challenge 1 Hard

Create a complete graph K4 and derive its incidence matrix and the product with its transpose.

💡 Hint: Remember that K4 will have edges connecting every vertex to every other vertex.

Challenge 2 Hard

Given a graph structure with 5 vertices and 4 edges, provide potential incidence matrices and calculate their products.

💡 Hint: Draw the graph and note its edges before constructing the incidence matrix.
