Write the maximum number of points of intersection of 8 straight lines in a plane.

Explanation

To find the maximum number of points of intersection of 8 straight lines in a plane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Intersection Points**:
- When two lines intersect, they create one point of intersection. To maximize the number of intersection points, we need to ensure that no two lines are parallel and no three lines meet at the same point.

2. **Choosing Lines**:
