The data provided here are conditional based on the conjectures made in [3].
We denote the space of cusp forms on ${\rm Sp}(6,\Z)$ of weight $(j,k,l)$ by $S_{j,k,l}$. Here the weight $(j,k,l)$ refers to the irreducible representation of ${\rm GL}(3)$ of highest weight $(j+k+l,k+l,l)$; scalar-valued modular forms are of weight $(0,0,l)$.
For chosen weight $(j,k,l)$ with $l\geq 4$ and $j+2k+3l-6 \leq 80$ you can click "look up" to get the following data:
For 5) note that our convention for $T(q)$ is different from the usual one; we use the notation from the paper [3], Section 10, where the relation with the usual definition of $T(q)$ is explained. For the meaning of the space of lifts we also refer to the paper [3].
There is no data available for these values of $j$, $k$ and $l$.
