资源简介:
This integer sequence was registered and published in the On-Line Encyclopedia of Integer Sequences (OEIS.org) Database on October 14 - 2024, under the OEIS code: A377045.This sequence can be expressed with the help of two general formulas that uses the sequences:1) A000041: a(n) is the number of partitions of n (the partition numbers).2) A002407: Cuban primes: primes which are the difference of two consecutive cubes.3) A121259: Numbers k such that (3*k^2 + 1)/4 is prime.The two aforementioned general formulas are as follows: a(n) = A000041(A002407(n)). (1)a(n) = A000041((3*A121259 (n)^2+1) / 4). (2)Some interesting properties of this sequence are:◼ Number of partitions of prime numbers that are the difference of two consecutive cubes.◼ Number of partitions of primes p such that p=(3*n^2 + 1) / 4 for some integer n (A121259).◼ a(13) = ~1.49910(x10^43).◼ The last known integer n in A121259 is 341 and corresponds to a(60) = ~1.59114(x10^323).The numerical data showed on this dataset was generated by the following Mathematica program:PartitionsP[Select[Table[(3 k^2 + 1)/4, {k, 500}], PrimeQ]] The previous program was builded on Mathematica v13.3.0.Note: More mathematical details, graphics and technical information can be found in the notebook (.nb) & pdf files provided in this data pack.
