We don't know yet. As of now,everything past DAN is not well-defined since there is an infinite loop in WDEN,but even DAN itself is quite strong. So far sDAN has been analysed by Hyp Cos up to $$C(C(\Omega_2 3,0),0)$$ in TON,but there is still a lot more until we reach the limit of sDAN,let alone DAN,let alone parts after DAN (When Hyp Cos redefines WDEN). I'm pretty sure that in the world of computable notations,SAN is the best we got.
