Igusa class polynomials computation for class number 20,016

Participant : Emmanuel Thomé [contact] .

In collaboration with the Lfant project-team, Emmanuel Thomé and Andreas Enge completed the computation of Igusa class polynomials for a quartic CM field whose Igusa class number is 20,016. That is more than 20 times more than the previous state of the art. This has been made possible with the CMH software, which corresponds to the article [10] .
