We carry out a systematic study of 4d 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 S(r)G,ℓ for ℓ = 2,3,4 and T(r)G,ℓ for ℓ = 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.
