 OFFSET 1,2 COMMENTS This sequence is to A003215 as A002828 is to A000290, and as A061336 is to A000217. LINKS Lars Blomberg, Table of n, a(n) for n = 1..10000 EXAMPLE a(21) = 3, because 21 = 19 + 1 + 1 = 7 + 7 + 7, so there are two ways to express 21 as the sum of 3 hex numbers, but no way to express 21 as the sum of 2 hex numbers.
