Exotic newforms constructed from a linear combination of eta quotients

K{ö}hler, in [1], presented a weight 1 newform on ${\mathrm{\Gamma }}_0(576)$ constructed from a linear combination of weight 1 eta quotients and asked, ``What would be a suitable $L$ and representation $\rho$ such that Deligne$\text{-}$Serre correspondence holds?" In this paper, we find the Galois field extension $L$ and representation $\rho$ such that the Deligne$\text{-}$Serre correspondence holds for this newform, and also study the splitting of primes in $L$ using the coefficients $a(p)$ of the newform. We also discuss an exotic newform on ${\mathrm{\Gamma }}_0(1080)$ constructed from a linear combination of weight 1 eta quotients, find the corresponding Galois extension and representation, and study the splitting of primes in this extension. Furthermore, we find all such newforms that can be constructed from a linear combination of weight 1 eta quotients listed in [2] with $q$-expansion of the form $q+{\sum }_{k=2}^{\mathrm{\infty }}a(k)q^k$.
