distinct terms only ignore palindromes like 11,22 ignore reversals with leading zero, like 10→1 non-trivial only

Resume tip: use Stop after current n1. The generator finishes that complete group and displays the Next n1. Enter that value in Start from n1 on the next day. It is also remembered automatically in this browser.

For large searches, download the results before closing the page. The method uses Δ(n)=n²−rev(n)² and searches for groups where the total Δ is 0.
