We discuss several j-function formulas that uses some of Ramanujan's continued fractions, in particular the cubic one.
In a previous paper, two of these c-fractions were connected to the symmetry groups of Platonic solids, namely the icosahedral and octahedral groups. In this paper, we propose a connection between the cubic continued fraction and the tetrahedral group.
A method will also be given to find modular relations between a continued fraction's argument q and q^n using the n-tuplication formulas for the j-function, for n such that n-1 divides 24.
