SUMMARY
The discussion clarifies that there is a distinction between \( l_{\infty} \) and \( l^{\infty} \). The notation \( l^{\infty} \) refers specifically to the space of bounded sequences, while \( l_{\infty} \) is often used interchangeably but can imply a different context. The more common notation for this space is indeed \( \ell^{\infty} \), which denotes the set of all bounded infinite sequences.
