 OFFSET 1,1 COMMENTS See A043291 and A033001 through A033014 for the analog in other bases, A033015 - A033029 for the variants with run lengths >= 2. - M. F. Hasler, Feb 02 2014 Numbers without repeating adjacent digits for which all digits are divisible by 13, in base 144. Consequently there are 11^n n-digit members of this sequence (base 144) and so (11^(n+1)-1)/10 members of this sequence below 144^n. - Charles R Greathouse IV, Feb 02 2014 LINKS Vincenzo Librandi, Table of n, a(n) for n = 1..1400 FORMULA a(n) = 13*A043316(n) (= 13*n for n<12). - M.
