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.
Our research “Testing Chebyshev’s bias for prime numbers up to 1015” won the top award at the “Step Into The Future” science forum and will be presented at the 30th European Union Contest for Young Scientists 2018 in Dublin (Ireland) on September 14-19, 2018. The EUCYS was set up at 1989 to promote the ideals of co-operation and interchange between young scientists. The contest is the annual showcase of the best of European student scientific achievement. The Russian team of 3 students will compete among other students from 43 countries.
In addition, our research got the right to be presented at Intel ISEF final that is held in the USA every year.
Our research work “Testing Chebyshev’s bias for prime numbers up to 1015” won “Step Into The Future” all-Russian science forum (a part of international Intel ISEF competition) that took place in Moscow on March 19-23, 2018. Continue reading →
Our presentation “Testing Chebyshev’s bias for prime numbers up to 1015” won “The best presentation in English” award at the “Step Into The Future” all-Russian science forum that took place in Moscow on March 19-23, 2018.
Our research presentation “Testing Chebyshev’s bias for prime numbers up to 1015” became the only winner of the “Mathematics and its applications in modern technologies” section of “Step Into The Future” science forum that took place in Moscow on March 19-23, 2018. Continue reading →
We are publishing the short presentation of our paper called “The Practical Realization of a Cryptographic System Based on One-Time Pads” (in Russian) that won the top award in the Computer Science section of the Intel-Avangard conference (the part of Intel ISEF) on February 22-25, 2018.
On February 25, 2018 our cryptography paper and presentation “On practical realization of one-time pad cryptographic system” won the top award in the Computer Science section at Intel-Avangard conference, which is a part of international Intel ISEF competition. Continue reading →
On September 22, 2017 our data on number of steps in Collatz sequence for Mersenne primes were included in OEIS as an addition to A181777. Prior to this A181777 contained information up to the 42nd Mersenne prime only. Continue reading →
As we announced before, on April 23rd, 2017 our “1003 Palindrome Generator”, using proprietary theoretical algorithm, generated 108864 (one hundred and eight thousand eight hundred sixty four) 19-digit delayed palindromes with 261-step delay before achieving the 119-digit palindrome, each of which was independently tested and confirmed its properties.
