 OFFSET 1,1 COMMENTS Positions of 3 in A277544. Numbers having 3 as rightmost nonzero digit in base 6.  This is one sequence in a 5-way splitting of the positive integers; the other four are indicated in the Mathematica program.  Every term is a multiple of 3; see A277573. Numbers m having the property that tau(3m) < tau(2m) where tau(m) = A000005(m) (i.e., the number of divisors of m). - Gary Detlefs, Jan 28 2019 LINKS Clark Kimberling, Table of n, a(n) for n = 1..10000 FORMULA a(n) = 5n + O(log n). - Charles R Greathouse IV, Nov 03 2016 MAPLE with(numtheory): for n from 1 to 279 do if tau(3*n)
