Define the sequence a(n) as the number of adjacent pairs of ones in the binary expansion of n (possibly overlapping).
E.g.: a(5) = a(101₂) = 0, a(6) = a(110₂) = 1, a(7) = a(111₂) = 2

Define the sequence b(n) = (-1)^a(n).
This sequence is called the Rudin-Shapiro sequence.

Also consider the summatory sequence of b(n): .

The first couple of values of these sequences are:
n    &nbsp   0 &nbsp   1 &nbsp   2 &nbsp   3 &nbsp   4 &nbsp   5 &nbsp   6 &nbsp   7
a(n) &nbsp   0 &nbsp   0 &nbsp   0 &nbsp   1 &nbsp   0 &nbsp   0 &nbsp   1 &nbsp   2
b(n) &nbsp   1 &nbsp   1 &nbsp   1 &nbsp  -1 &nbsp   1 &nbsp   1 &nbsp  -1 &nbsp   1
s(n) &nbsp   1 &nbsp   2 &nbsp   3 &nbsp   2 &nbsp   3 &nbsp   4 &nbsp   3 &nbsp   4

The sequence s(n) has the remarkable property that all elements are positive and every positive integer k occurs exactly k times.

Define g(t,c), with 1 ≤ c ≤ t, as the index in s(n) for which t occurs for the c'th time in s(n).
E.g.: g(3,3) = 6, g(4,2) = 7 and g(54321,12345) = 1220847710.

Let F(n) be the fibonacci sequence defined by:
F(0)=F(1)=1 and
F(n)=F(n-1)+F(n-2) for n>1.

Define GF(t)=g(F(t),F(t-1)).

Find ΣGF(t) for 2≤t≤45.
