OEIS Sequences

For k in {2,3,...,9} define a sequence as follows: a(0)=0; for n>=0, a(n+1)=a(n)+1, unless a(n) ends in k, in which case a(n+1) is obtained by replacing the last digit of a(n) with the digit(s) of k². This is k(9). A237346

Squarefree products of k primes that are symmetrically distributed around their average. Case k = 4. A294751

Number of distinct values of the (n-1)st difference of permutations of 1..n. A130803

a(n) = (8·10ⁿ - 71)/9 for n > 0. A173810

Binomial transform of [1, 3, 4, 3, 2, 0, 0, 0, ...]. A136395

If A056239(m) = n, then a(n) is the maximum value of A000005(m). A88881
