  Mortensen introduced a connexive logic commonly known as 'M3V'. M3V is
obtained by adding a special conditional to LP. Among its most notable
features, besides its being connexive, M3V is negation-inconsistent and it
validates the negation of every conditional. But Mortensen has also studied and
applied extensively other non-connexive logics, for example, closed set logic,
CSL, and a variant of Sette's logic, identified and called 'P2' by Marcos.
  In this paper, we analyze and compare systematically the connexive variants
of CSL and P2, obtained by adding the M3V conditional to them. Our main
observations are two. First, that the inconsistency of M3V is exacerbated in
the connexive variant of closed set logic, while it is attenuated in the
connexive variant of the Sette-like P2. Second, that the M3V conditional is,
unlike other conditionals, "connexively stable", meaning that it remains
connexive when combined with the main paraconsistent negations.
