%N A125652 Numbers m such that m^2=A125650(k) for some k (belonging A125651).
%C A125652 Indices k such that a(n)^2=A125650(k) are listed in A125651.
%C A125652 3 divides a(n) for n>1. For n>1 a(n) = 3*A041053(2n-3), where A041053(n) = {1, 1, 2, 3, 32, 35, 67, 102, 1087, 1189, 2276, 3465, ...} Denominators of continued fraction convergents to sqrt(32). - _Alexander Adamchuk_, Jan 19 2007
%F A125652 a(2k)=A106328(2k); for k>0, a(2k+1)=A106328(2k+1)/2.
%F A125652 a(n) = sqrt(A125650(A125651(n))).
%F A125652 a(n) = 3*A041053(2n-3) for n>1. - _Alexander Adamchuk_, Jan 19 2007
%e A125652 a(2)=3 because A125650(3)=9=3^2; a(3)=9 because A125650(24)=81=9^2.
