 OFFSET 0,1 COMMENTS a(n) is divisible by 8. 2^(3+4k) divides a(4k) and a(4k+2). 8k divides a(4k-1). 4(4k+2) divides a(4k+1). - Alexander Adamchuk, Nov 18 2006 LINKS Harry J. Smith, Table of n, a(n) for n = 0..100 FORMULA a(n) = A007778(n+2) - A007778(n). - Alexander Adamchuk, Nov 18 2006 EXAMPLE a(1) = |0^1 - 2^3| = 8, a(2) = |1^2 - 3^4| = 80.
