Does anyone have an up to date 2026 version of Denis Simon's 2011 script 
"ell.gp" ??

I attach it here, but it is crashing, sorry to say, in the 
bnfell2descent routines.

I am trying to do some 2-cover optimizations for congruent number 
elliptic curves.

I am current running version 2.17.4

Sorry if this is too cryptic.

Randall
