Multiperfect numbers: Lists

This page is obsolete because Achim Flammenkamp has done a great job in maintaining an online list of all known MPFNs. Visit his page for the list and some history, statistics and graphs related to MPFNs.

For general information about multiperfect numbers (MPFNs), please see my main MPFN page.

Here's a graph showing the distribution of the size of known MPFNs for each index (as of early 1997; for a newer version, see Achim's page); I call it the "staircase" graph.
