For example, 7! = 15*16*21 = 14*18*20 is the case when absolute maximum of x (=15) and absolute minimum of z (=20) cannot be achieved together. - _Max Alekseyev_, Jun 18 2022 %D A061031 Luc Kumps, personal communication. %H A061031 Max Alekseyev, <a href="/A061031/b061031.txt">Table of n, a(n) for n = 3..100</a> %Y A061031 Cf.
