Decomposition of \(S_{16}^{\mathrm{new}}(\Gamma_1(6))\)

We only show spaces with even parity, since no modular forms exist when this condition is not satisfied. Within each space \( S_k^{\mathrm{new}}(N, \chi) \) we list available newforms together with their dimension.

Label	\(\chi\)	Newforms	Dimension	\(\chi\) degree
6.16.a	\(\chi_{6}(1, \cdot)\)	6.16.a.a	1	1
		6.16.a.b	1
		6.16.a.c	1
