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 generated delayed palindromes was independently tested by our “1002 Palindrome List Tester” that fully confirmed its properties.

Before January 1st, 2017 there had been just one publicly known 260-step large delayed palindrome – the number 1003062289999939142, discovered on March 19th, 2006 by the international group of mathematicians and programmers after many years of calculations.

As reported before, on January 23rd, 2017 we announced the registration of 225 (two hundred and twenty five) 259-step delayed palindromes discovered by us in The On-Line Encyclopedia of Integer Sequences under А281390. This became the first  significant discovery in the area of delayed palindromes in a decade.

We will publish the full list of discovered delayed palindromes in the near future.
