As we announced before, on April 22nd, 2017 our “1003 Palindrome Generator”, using proprietary theoretical algorithm, generated 430080 (four hundred and thirty thousand and eighty) 19-digit delayed palindromes with 260-step delay before achieving the 119-digit palindrome, each of which was independently tested and confirmed its properties.

On May 12, 2017 we officially filed all 430080 (four hundred and thirty thousand and eighty) 19-digit 260-step delayed palindromes with The Online Encyclopedia of Integer Sequences (OEIS) as the new sequence А286481 . The published sequence starts with 1003062289999939142 and ends with 3419399999822603000.

All discovered delayed palindromes are currently available for download from OEIS as well as from our data repository.

The published sequence is complete – there is a theoretical confirmation for its size, composition and completeness.
