Abstract Let s(n) be the side of the smallest square into which we can pack n unit squares. We present a history of this problem, and give the best known upper and lower bounds for s(n) for nâ¤100, including the best known packings. We also give relatively simple proofs for the values of s(n) when n = 2, 3, 5, 8, 15, 24, and 35, and more complicated proofs for n=7 and 14. We also prove many other l
