| Summary:

We carry out a systematic study of 4d $mathcal{N} = 2$ preserving S-folds of
F-theory 7-branes and the worldvolume theories on D3-branes probing them. They
consist of two infinite series of theories, which we denote following the
original papers by $mathcal{S}^{(r)}_{G,ell}$ for $ell = 2,3,4$ and
$mathcal{T}^{(r)}_{G,ell}$ for $ell = 2,3,4,5,6$. Their distinction lies in
the discrete torsion carried by the S-fold and in the difference in the
asymptotic holonomy of the gauge bundle on the 7-brane. We study various
properties of these theories, using diverse field theoretical and string
theoretical methods.
