COMMENT
|
The sequence of complex numbers (which this sequence is part of) appears to converge to
1.529085513635746125160990523790225210619365... + i*0.74293413587832283909143193794726628109624299200...
Using Plouffe's Inverter, http://pi.lacim.uqam.ca/eng/, yields
Roots of polynomials of 5th degree (coeffs: -9..9) 1529085513635746 = 1+1*x-4*x^2-6*x^3+4*x^4+4*x^5
Roots of polynomials of 5th degree (coeffs: -9..9) 7429341358783228 = 1+5*x+4*x^2-2*x^3-4*x^4-4*x^5
