comment Characterization of entire functions to be a polynomial
@user64494 That depends. Casorati-Weierstrass is elementary, and if you have taken topology before complex analysis, you probably know Baire's category theorem. Anyway, the OP wanted to avoid big Picard, not necessarily replace it with something simpler.

comment Show that we can only find $6$ biholomorphic mappings $\phi$.
@kimtahe6 You should have no trouble showing that $\phi_k$ is 1-1 and finding its inverse.

comment Show that we can only find $6$ biholomorphic mappings $\phi$.
@kimtahe6 Which part are you having problems with? It's almost self-evident that each $\phi_k$ is a biholomorphism, and that $\phi_k$ maps $M$ into $M$ follows from what I wrote.
