On April 21st, 2017 our “1003 Palindrome Generator”, using proprietary theoretical algorithm, generated 1620000 (one million six hundred twenty thousands) 19-digit delayed palindromes with 259-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 259-step large delayed palindrome – the number 1000000079994144385, discovered on November 28th, 2005 by the international group of mathematicians and programmers after many years of calculations.
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.
