We can use Warshall’s algorithm for finding the Transitive Closure of a matrix. By using the formula below we can construct The Relation matrix $R^{1}$ from $R^{0}$.

$R^{1}[i,j]=R^{0}[i,j] OR (R^{0}[i,k] and R^{0}[k,j])$

where $R^{0}$ is the adjacency matrix of given data. k is the relation degree.

For Given data the adjacency matrix $R^{0}$ is given below.

By using the formula mentioned above, Consider the first row and first column, The matrix $R^{1}$ will be:

So $R^{4}$ will be the transitive closure of the given data.

Hence the solution provided.
