%N Factorial splitting: write n! = x*y*z with x <= y <= z and minimal z-x; sequence gives value of z-x.
%C a(n) <= A061033(n).
%C n=61 gives the smallest example where the value of x is not maximal (cf. A061030) and the value of z is not minimal.
%C 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.
