I thought about tribonacci as well.
say, we got the fib:
1, 1, 2, 3, 5, etc.
1 = 1
1 + 2^2 = 5
1 + 2^2 + 3^2 = 14 (which is half of 28.)
or
1 + 3^3 = 28, though doesn't make sense or a pattern, really. Besides, 4^5 or 5^4 is way higher than 260.
now, trib:
1, 1, 1, 3, 5, 9, 17, 31, 57, 105, 193
57 + 193 = 260, though, that may just be a coincidence. Most likely.
