Are there any shared features between gta online and story mode?

The verified evidence describes Grand Theft Auto V's single-player story mode, including its three protagonists, open-world setting in San Andreas, and narrative elements like heists and corrupt agencies. However, the evidence contains no details about GTA Online or its features. Without information about GTA Online's mechanics, gameplay elements, or systems, it is impossible to identify shared features between the online and story modes based solely on this source. Additional documentation about GTA Online would be required to provide a meaningful comparison.
