genus2reduction binary package in Ubuntu Precise i386

 genus2reduction is a program for computing the conductor and
 reduction types for a genus 2 hyperelliptic curve.
 .
 As an example of genus2reduction's functionality, let C be a proper smooth
 curve of genus 2 defined by a hyperelliptic equation y^2+Q(x)y=P(x), where
 P(x) and Q(x) are polynomials with rational coefficients such that
 deg(Q(x))<4, deg(P(x))<7. Let J(C) be the Jacobian of C, let X be the minimal
 regular model of C over the ring of integers Z.
 .
 This program determines the reduction of C at any prime number p (that
 is the special fiber X_p of X over p), and the exponent f of the conductor
 of J(C) at p.
