On October 1, 2019 a well-known American mathematician Stephen Wolfram announced “Wolfram Rule 30 Prizes” science competition.
The competition is devoted to the solution of the so-called “Rule 30” – one of the unsolved math problems from a cellular automaton area.
Our sequence of 19353600 record 288-step delayed palindromes is published as A326414 .
The sequence starts with 12000700000025339936491 (the number discovered by Rob van Nobelen on April 26, 2019), ends with 29463993352000000700020 and contains all terms known at present.
We publish our first data on the Collatz function for 237156667 – 1 (#7 known megaprime) and two of its odd neighbors located at ±26.
We publish our first data on the Collatz function for 232582657 – 1 (#8 known megaprime) and two of its odd neighbors located at ±71149323674102624414.
We publish our first data on the Collatz function for 10223×231172165 + 1 (#9 known megaprime) and two of its odd neighbors located at ±4.
We publish our first data on the Collatz function for 230402457 – 1 (#10 known megaprime) and two of its odd neighbors located at ±2.
On 26 April 2019, Rob van Nobelen discovered the 23-digit number 12000700000025339936491 – the first one that takes record-breaking 288 steps to reach a final 142-digit palindrome. The previous record (261 steps) was set in 2005.
We expanded the found number to a sequence with 19353600 terms in total. This sequence currently includes all known 288-step delayed palindromes.
All results are contributed to OEIS and will be published in due course.
