Find all pairs $ (m,n)$ of integer numbers $ m,n > 1$ with property that $ mn \minus{} 1\mid n^3 \minus{} 1$.
To find all pairs \((m, n)\) of integer numbers \(m, n > 1\) such that \(mn - 1 \mid n^3 - 1\), we will proceed as follows:

1. **Express the divisibility condition:**
   \[
   mn - 1 \mid n^3 - 1
   \]
   This means there exists an integer \(k\) such that:
   \[
   n^3 - 1 = k(mn - 1)
   \]

2. **Rewrite the equation:**
   \[
   n^3 - 1 = kmn - k
   \]
   Rearrange to:
   \[
   n^3 - kmn = k - 1
   \]

3. **Factorize \(n^3 - 1\):**
   \[
   n^3 - 1 = (n - 1)(n^2 + n + 1)
   \]
   Therefore, we need:
   \[
   mn - 1 \mid (n - 1)(n^2 + n + 1)
   \]

4. **Consider the possible values of \(m\):**
   - If \(m = n\), then:
     \[
     mn - 1 = n^2 - 1
     \]
     and:
     \[
     n^3 - 1 = (n - 1)(n^2 + n + 1)
     \]
     Clearly, \(n^2 - 1 \mid (n - 1)(n^2 + n + 1)\) because \(n^2 - 1 = (n - 1)(n + 1)\).

   - If \(m = n^2\), then:
     \[
     mn - 1 = n^3 - 1
     \]
     and:
     \[
     n^3 - 1 \mid n^3 - 1
     \]
     which is trivially true.

5. **Check other values of \(m\):**
   - If \(1 < m < \sqrt{n}\), then:
     \[
     0 < \frac{n - m^2}{mn - 1} < 1
     \]
     which is not an integer.
   - If \(\sqrt{n} < m \leq n\), then:
     \[
     -1 < \frac{n - m^2}{mn - 1} < 0
     \]
     which is not an integer.
   - If \(n < m < n^2\), then:
     \[
     0 < \frac{n^2 - m}{mn - 1} < 1
     \]
     which is not an integer.
   - If \(m > n^2\), then:
     \[
     -1 < \frac{n^2 - m}{mn - 1} < 0
     \]
     which is not an integer.

Therefore, the only possible pairs \((m, n)\) are \((k, k^2)\) and \((k^2, k)\) for any integer \(k > 1\).

The final answer is \( \boxed{ (m, n) = (k, k^2) } \) and \((m, n) = (k^2, k)\) for any integer \(k > 1\).
