**Title: Finding a Counterexample for Property 8 in Matrix Algebra**

To understand certain properties of matrix operations, we need to find an example where the property does not hold. Specifically, we are looking to demonstrate a situation where:

\[
(C \cdot d) \otimes A \neq (C \otimes A) \oplus (d \otimes A)
\]

Here, the goal is to identify a matrix \( A \) and constants \( c \) and \( d \) that satisfy the inequality above.

**Steps to Approach:**

1. **Matrix Selection:**
   - The matrix should be defined to include the left-hand side of the equation.
   - **Left-Hand Side (LHS):** 
     \[
     (C \cdot d) \otimes A
     \]
   - **Right-Hand Side (RHS):**
     \[
     (C \otimes A) \oplus (d \otimes A)
     \]

2. **Constants Definition:**
   - \( c \): a scalar
   - \( d \): a scalar

3. **Matrix Definition:**
   - \( A \) is a matrix with entries such that each row is separated by semicolons.

4. **Solution Structure:**
   - **LHS:** Represented as:
     \[
     \left[ \text{Entries in matrix form} \right]
     \]
   - **RHS:** Represented as:
     \[
     \left[ \text{Entries in matrix form} \right]
     \]

This setup aims to demonstrate the inequality graphically or numerically by substituting specific values. The objective is to identify and define \( A \), \( c \), and \( d \) such that the property fails, thus providing a counterexample for further learning and discussion on the limitations of matrix properties in certain conditions.
