It looks like sequence A147316 was retired in favor of A000045 on Feb 05
2011. The original sequence was:

A000045 Fibonacci mirror sequence Binet: f(n)=(1/5)*2^(-n) ((5 - 2
*Sqrt[5]) (1 + Sqrt[5])^n + (1 - Sqrt[5])^n(5 + 2 * Sqrt[5])).
1597, -987, 610, -377, 233, -144, 89, -55, 34, -21, 13, -8, 5, -3, 2, -1,
1, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597

which appears to be a shifted version of A000045, the Fibonacci numbers.
