This image represents a **partially ordered set** (poset) visualized as a Hasse diagram. The elements in this poset are sets, each set containing some numbers (elements like {2, 5, 7}, {3, 7}, etc.). The lines (edges) between them indicate the partial order relation, with the smaller sets lower in the diagram and larger sets higher. The goal is to find a **linear extension** of this poset, which is a total order that is consistent with the partial order.

### Steps to find the linear extension:
1. **Identify minimal elements**: These are the elements at the bottom of the diagram that have no elements below them.
2. **Move upwards through the diagram**, ensuring that each element is placed after all elements that are smaller than it in the partial order.

#### Analysis of the diagram:
- The minimal elements are the sets `{2}`, `{3}`, and `{2, 5}`.
- Next, `{3, 7}` and `{2, 5, 7}` are larger than `{3}`, and `{2, 5, 25}` is larger than `{2, 5}`.
- Finally, `{2, 3, 11}` is above both `{2}` and `{3}`.

### Linear extension:
One possible linear extension consistent with this partial order is:

\[
\{2\}, \{3\}, \{2, 5\}, \{3, 7\}, \{2, 5, 25\}, \{2, 3, 11\}, \{2, 3, 5, 7\}
\]

This is one possible total ordering, but other valid linear extensions may exist depending on the ties between elements at the same level.
