Any idea how big list of numbers you actually want to partition. Or its just 18.

comment A problem with polynomial root finding
@Zhong if in Linux try building MPSolve which can be found poisson.phc.unipi.it/~robol/trac. And if there is some cross platform C wizard among us probably building it in Windows is also possible sage.math.washington.edu/home/wstein/www/home/jason/…

Its kind of an all in one math antibiotic for your Intel processor kernel ;)

@Mr.Wizard “We are all failures- at least the best of us are.” I am always looking for more and more of this madness of yours! Keep running fast like those quasars :-)

comment Strange NSum behavior
@Artes This gives probably wrong result as you can cross check exp = Sum[(i + 1)/(i + 2) LegendreP[i, 0] LegendreP[i, 0], {i, 0, k}]; exp /. k -> 30000 // N with the result your code gives!

But see here SumConvergence[(i + 1)/(i + 2) LegendreP[i, 0] LegendreP[i, 0], i, Assumptions -> Element[i, Integers] && Mod[i, 2] == 0]!

You are welcome. The trick if you are new with Mathematica is be persistent and do not loose hope quickly!
