Default Near-repdigit 5(1)w

Is there a reason why Near-repdigit 5(1)w is not listed in the factor tables?

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: http://homepage2.nifty.com/m_kamada/...orizations.htm
