A061030) and the value of z is not minimal. %C A355192 Apparently we have x < y < z for all n > 9. If so, using strict inequalities x < y < z in the definition would make the sequence undefined for n < 3 and affect only a(9) by switching from 9! = 70*72*72 to 9! = 63*72*80. %H A355192 Max Alekseyev, <a href="/A355192/b355192.txt">Table of n, a(n) for n = 0..100</a> %Y A355192 Cf.
