Local data
This elliptic curve is semistable. There are 5 primes of bad reduction:

---|---|---|---|---|---|---|---|
\(2\) | \(2\) | \(I_{2}\) | Split multiplicative | -1 | 1 | 2 | 2 |
\(3\) | \(2\) | \(I_{2}\) | Split multiplicative | -1 | 1 | 2 | 2 |
\(5\) | \(6\) | \(I_{6}\) | Split multiplicative | -1 | 1 | 6 | 6 |
\(7\) | \(2\) | \(I_{6}\) | Non-split multiplicative | 1 | 1 | 6 | 6 |
\(23\) | \(4\) | \(I_0^{*}\) | Additive | -1 | 2 | 6 | 0 |
Galois representations
The image of the 2-adic representation attached to this elliptic curve is the subgroup of $\GL(2,\Z_2)$ with Rouse label X8.
This subgroup is the pull-back of the subgroup of $\GL(2,\Z_2/2^1\Z_2)$ generated by $$ and has index 6.
The mod \( p \) Galois representation has maximal image \(\GL(2,\F_p)\) for all primes \( p \) except those listed.

An entry - indicates that the invariants are not computed because the reduction is additive.
Isogenies
This curve has non-trivial cyclic isogenies of degree \(d\) for \(d=\)
2, 3 and 6.
Its isogeny class 111090dd
consists of 4 curves linked by isogenies of
degrees dividing 12.
