EXAMPLE
Let s(x) = x*x^(1/x), r(x) = round(s(x)), d(x) = abs(s(x)-r(x));
a(1) = 2:
s(2) = 2.8284271...,
r(2) = A291212(1) = 3,
d(2) = 0.17157...;
a(2) = 5:
s(5) = 6.8986483...,
r(5) = A291212(2) = 7,
d(5) = 0.10135169...;
a(3) = 6:
s(6) = 8.0880369...,
r(6) = A291212(3) = 8,
d(6) = 0.08803692...;
a(4) = 15:
s(15) = 17.96790087...,
r(15) = A291212(4) = 18,
d(18) = 0.03209912...;
a(5) = 16:
