http://revue.sesamath.net/spip.php?article1581 WebSierpinski conjectured that every multiplicity´ k > 2is possible, and we deduce this from the Prime k-tuples Conjecture. We also make some progress toward an older conjecture of Carmichael, which states that no totient has multiplicity 1. The lower bound for a possible counterexample is extended to 101010 and the bound liminf
The Prime Glossary: Sierpinski number - PrimePages
If we take n to be a negative integer, then the number k2 + 1 becomes $${\displaystyle {\frac {2^{ n }+k}{2^{ n }}}}$$. When k is odd, this is a fraction in reduced form, with numerator 2 + k. A dual Sierpinski number is defined as an odd natural number k such that 2 + k is composite for all natural … See more In number theory, a Sierpiński number is an odd natural number k such that $${\displaystyle k\times 2^{n}+1}$$ is composite for all natural numbers n. In 1960, Wacław Sierpiński proved that there are See more The Sierpiński problem asks for the value of the smallest Sierpiński number. In private correspondence with Paul Erdős, Selfridge conjectured that 78,557 was the smallest Sierpiński number. No smaller Sierpiński numbers have been discovered, and it is now … See more A number may be simultaneously Sierpiński and Riesel. These are called Brier numbers. The smallest five known examples are … See more The sequence of currently known Sierpiński numbers begins with: 78557, 271129, 271577, 322523, 327739, 482719, 575041, 603713, 903983, 934909, 965431, 1259779, 1290677, 1518781, 1624097, 1639459, 1777613, 2131043, 2131099, 2191531, … See more In 1976, Nathan Mendelsohn determined that the second provable Sierpiński number is the prime k = 271129. The prime Sierpiński … See more Suppose that both preceding Sierpiński problems had finally been solved, showing that 78557 is the smallest Sierpiński number and that 271129 is the smallest prime Sierpiński … See more • Mathematics portal • Cullen number • Proth number • Riesel number • Seventeen or Bust • Woodall number See more WebThe Sierpinski's conjecture states that for all integer $n>1$, we have $\frac{5}{n}=\frac{1}{a}+\frac{1}{b}+\frac{1}{c}$ where $(a,b,c) \in \mathbb{N}_*^3$.
