14. Given a set of points on a plane $P=\left\{P_{1}, P_{2}, \cdots, P_{1994}\right\}$, where no three points in $P$ are collinear. Divide all the points in $P$ into 83 groups arbitrarily, such that each group has at least 3 points, and each point belongs to exactly one group. Then connect any two points in the same group with a line segment, and do not connect points in different groups, thus obtaining a pattern $G$. Different grouping methods result in different patterns. Let the number of triangles in the pattern $G$ with vertices from the points in $P$ be denoted as $m(G)$, find the minimum value of $m(G)$, denoted as $m$.
14. Let \( m(G) = m_0, G \) is obtained from groups \( X_1, X_2, \cdots, X_{83} \), where \( X_i \) is the set of points in the \( i \)-th group, \( i = 1, 2, \cdots, 83 \), then \( |X_1| + |X_2| + \cdots + |X_{83}| = 1994 \), and \( m_0 = C_{x_1}^3 + C_{x_2}^3 + \cdots + C_{x_{83}}^3 \).
We will prove that for \( 1 \leqslant i \neq j \leqslant 83 \), \( ||x_i| - |x_j|| \leqslant 1 \).
In fact, if there exist \( i, j \) such that \( |x_i| \geqslant |x_j| + 2 \), then moving one point from \( X_i \) to \( X_j \) results in a partition that meets the requirements, and for such a partition, the graph \( G^1 \) obtained has \( m(G^1) \) reduced by \( \left(C_{|x_i| - 1}^2 - C_{|x_j|}^2\right) \) triangles.
Since \( |x_j| \leqslant |x_i| - 2 \), \( C_{|x_i| - 1}^2 - C_{|x_j|}^2 > 0 \), which contradicts the minimality of \( m_0 \).
Also, \( 1994 = 83 \times 24 + 2 = 81 \times 24 + 2 \times 25 \), hence \( 81 C_{24}^3 + 2 C_{25}^3 = 168544 \).
