To find the number of subsets of a given set, we use the formula:

$\text{Number of subsets} = 2^n$

where $n$ is the number of elements in the set.

For the set $\{2, 11, 6\}$, there are 3 elements. So, we have:

$\text{Number of subsets} = 2^3 = 8$

Therefore, the set $\{2, 11, 6\}$ has 8 subsets.

List of all subsets:

1. $\{\}$ (the empty set)
2. $\{2\}$
3. $\{11\}$
4. $\{6\}$
5. $\{2, 11\}$
6. $\{2, 6\}$
7. $\{11, 6\}$
8. $\{2, 11, 6\}$
