I tested this. AFter putting the large seadata files into that place the code sage: p 10566623376041669505825220895462627801380145726624712771836144280024219722297939525451022774579043146020265329009462778097121538072213487555318041328039599 sage: a4 6557325753041215216697541661243177462316789827714644669153173743634615853451990973713919498189870050066222585898470391225455349541996119434962754618249308 sage: a6 3887529832007272230349363633177495741990999092935596186265775681498612008751646149414901742385996951003068331698140100902826619262789957720578797201032523 sage: E = gp.ellinit([0,0,0,a4,a6]) sage: sage: ap = E.ellap(p) runs fine.
