EXAMPLE
a(6)=192 because the minimum numerator among permutations of
(1,1,2,4,16) happens when the continued fraction is [1:4,2,16,1]=192/157 or
[1:16,2,4,1]=192/181.
MATHEMATICA
a[1] = 1; a[n_] := a[n] = Union[ Numerator /@ FromContinuedFraction /@ Permutations[ Table[ a[i], {i, n - 1}]]] [[1]]; Table[ a[n], {n, 11}]
