pari-elldata 0.20190911-1 (s390x binary) in ubuntu focal

 PARI/GP is a widely used computer algebra system designed for fast
 computations in number theory (factorizations, algebraic number theory,
 elliptic curves...), but also contains a large number of other useful
 functions to compute with mathematical entities such as matrices, polynomials,
 power series, algebraic numbers, etc., and a lot of transcendental functions.
 PARI is also available as a C library to allow for faster computations.
 .
 Originally developed by Henri Cohen and his co-workers (University Bordeaux I,
 France), PARI is now under the GPL and maintained by Karim Belabas with the
 help of many volunteer contributors.
 .
 This package contains the optional PARI package elldata which provides
 the Elliptic Curve Database of J. E. Cremona Elliptic which can be queried by
 ellsearch and ellidentify.
