Can gta v story mode and gta online characters meet?

The evidence provided is from the Wikipedia article for Grand Theft Auto IV, which is a 2008 game. This article does not discuss GTA Online, GTA V, or any interaction between single-player and online modes. GTA Online is a separate 2013 expansion for GTA V, which has different characters and storylines. Since the evidence contains no information about GTA V or GTA Online, no verification can be made about character interactions between story mode and online modes. Any claims about such meetings would require evidence from GTA V or GTA Online sources, which are not included here.
