Decomposition of $S_{7}^{\mathrm{new}}(\Gamma_1(23))$

We only show spaces with odd 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
23.7.b	$\chi_{23}(22, \cdot)$	23.7.b.a	1	1
		23.7.b.b	2
		23.7.b.c	8
23.7.d	$\chi_{23}(5, \cdot)$	23.7.d.a	110	10
