My question is closely related to the following [topic](https://stackoverflow.com/questions/57210753/find-common-values-in-multiple-lists).
I have a number of lists and I want to find the lists that share common values. All lists have the same size. The total number of lists is variable and can increase. Minimum number of lists is `2`

```
a = [1, 2, 3, 4]
b = [5, 6, 7, 8]
c = [9, 10, 11, 1]

```

The expected output is: 

```
[a, c]

```

Ideally, I also want the fastest method. Thanks in advance,
