Near-repdigit 5(1)w
 

Is there a reason why [URL="http://factordb.com/index.php?query=(46*10^x-1)%2F9"]Near-repdigit 5(1)w[/URL] is not listed in the [URL="http://factordb.com/tables.php?open=1"]factor tables[/URL]?

Some forms indeed are missed in the factordb table. You can email Markus -- he rarely visits here.

However, you can always use M.Kamada's pages; they are (semi-)manually curated and nothing is missed there: see

other forms, and of course, the top page: [URL]http://homepage2.nifty.com/m_kamada/math/factorizations.htm[/URL]
