Can you have 3x2 and 4x3 in gin rummy?

In gin rummy, you can have sets and runs of cards, but specific combinations like 3x2 and 4x3 do not apply directly. However, you can form a run of three cards in sequence (like 2-3-4) and a run of four cards in sequence (like 3-4-5-6) using the same suit or different suits. The focus is on forming valid melds rather than adhering to a numeric multiplication format.
