OEIS Sequences

Small-number statistic from the enumeration of domino tilings of a 7-pillow of order n. A112841

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(4). A237341

a(0) = 0, a(n) = previous term + repunit of length of previous term for n > 0. A247107
