Properties

Appears in sequences

• Numbers n such that with b=n*(2n-1) two remainders x and y are defined via x = 2^(b-1) -1 mod b and y = (2*n-1)^(b-1) - 1 mod b which satisfy x==y==0 (mod n) and y-x=n.at n=11A190638
• 0-additive sequence: a(n) is the smallest number larger than a(n-1) that is not the sum of any subset of earlier terms, starting with initial values {2, 5}.at n=30A244749
• Prime numbersat n=979527
