Query: Singular values of generalized $\lambda$ functions   We study special values of a modular function $\Lambda$ which is one of
generalized $\lambda$ functions. We show special values of $\Lambda$ at
imaginary quadratic points are algebraic integers. Further we prove that
$\Lambda$ and the modular invariant function generate the modular function
field with respect to the modular subgroup $\Gamma_1(N)$.
