Are there any aircraft with a 4-wheel nose landing gear and a 16-wheel main landing gear?
The Il-76:



4 main bogies with 4 wheels each, nose gear with 4 wheels.

this one has a better view of the wheels, but it's a CGI: 



4-wheel nose gear is rare, 16-wheel mains are more common: Boeing 747 (4 trucks with 4 wheels each in 2x2 config), Avro Vulcan (main trucks with 2 axles with 4 wheels each), HP Victor (same as Vulcan), Shorts Belfast (same as Vulcan).
