What do we call the numbers that cannot be arranged into 2-row arrays?

Question

The question begs for amplification. An array usually contains a set of some sort. There is not a hint in your question of what the set is.

My math homework question asks - exactly as stated - What do we call the numbers that cannot be arranged into 2-row arrays? - I want to say contemporary - but I am not sure. Please advise me if you can. Thanks
