I know this is a simple question, but I am really new to Mathematica.

If I have elements `a = {1, 2}` and `b = {2, 3}`, I can simply type

```
S = {{a}, {b}}

```

and get a set formed by 1-line matrices, `a` and `b`. But if I have 73 numbered elements,like `w1`, `w2`, ..., `w73`, this would take a while. With

```
S = Table[Symbol["w" <> ToString[i]], {i, 1, 73}]

```

I don't get exactly what I want. The output is like `{w1, ..., w73}` instead of `{{w1}, ..., {w73}}`.
