%N Decimal expansion of sqrt(3)-sqrt(2).
%C From _Bernard Schott_, Jan 16 2021: (Start)
%C Equals the smallest positive root of x^4 - 10*x^2 + 1 (minimal polynomial).
%C An approximation to 1/Pi (see corresponding comment in A135611). (End)
%F Equals A002194 - A002193.
%F Equals A135611 - A010466.
%F Equals 1/A135611. - _Bernard Schott_, Jan 15 2021
