Current description is indecipherable and there are too much missing information:

• Input list have at most depth 3
• 1st level is always a list; 2nd level can be a int or a list of ints
• Find all lists resulting from exploding 2nd level of each list; for every list of ints in 2nd level, they should be exploded as set product; then list all by order of appearance in the result
• Result should be a list of lists; sub-lists should be right-padded with 0 to the longest sub-list in the result
• Sub-lists should have minimal length 1
