Defining parameters

Level: \( N \) \(=\) \( 18 = 2 \cdot 3^{2} \)
Weight: \( k \) \(=\) \( 5 \)
Character orbit: \([\chi]\) \(=\) 18.a (trivial)
Character field: \(\Q\)
Newform subspaces: \( 0 \)
Sturm bound: \(15\)
Trace bound: \(0\)

Dimensions

There are no modular forms of weight 5 and character 18.a since the weight is odd while the character is even.
