As of my last update in 2023, the LEGO set referenced by the number 791902 does not directly correlate with any widely recognized or released LEGO set based on the standard numbering system employed by The LEGO Group for their product catalog. It is possible that there may be a misunderstanding or a typo in the set number provided.
LEGO sets are usually designated by unique numbers that identify specific kits, which can range from small, simple builds to large, complex models, covering a wide array of themes such as LEGO City, Star Wars, Technic, Creator, and many more. These sets are designed to spark creativity in builders of all ages, enabling them to construct vehicles, buildings, scenes, and characters out of the iconic LEGO bricks.
If you are looking for information on a specific LEGO set, please ensure the set number is accurate. It could also be helpful to include the theme or a brief description if the set number might be incorrect or if the set is particularly obscure or limited in release (such as promotional or regional exclusive sets).
