OEIS Sequences

Numbers without comma-successors: these are the numbers k such that if the commas sequence A121805 is started at k instead of 1, there is no second term. A367341

a(n) = A131668(n) - (2·n+1). A131766

(Sum of digits of n)⁵ - (sum of digits of n⁵). A69979

a(n) is the smallest number m such that the sum of the digits of n+m is n. A130692

Consider the Kaprekar map n->K(n) defined in A151949. Sequence gives numbers belonging to cycles of length greater than 1. A99010

There are exactly three primes among a(n+i) + a(n+j), 0 <= i < j <= 3, for any n >= 0: lexicographically earliest such sequence of distinct nonnegative integers. A329454

There are exactly three primes in {a(n+i) + a(n+j), 0 <= i < j <= 4} for any n >= 0: lexicographically earliest such sequence of distinct nonnegative integers. A329455
