Abstract

It is not known if any odd perfect numbers exist. Here we extend the computations in an earlier paper [100] to show that N > 10200.

Comments

There were two versions of this report. The first (given above) went to 10200, and the second went to 10240. Using new techniques described in [116], the lower bound was soon improved to 10300.
