Robert Israel, Table of n, a(n) for n = 1..10000

FORMULA

Is a(n)-floor(log(n)) bounded ?

EXAMPLE

(x-1)(x-2)(x-3) = x^3 - 6*x^2 + 11*x - 6, 11 is the largest coefficient for x^1, hence a(3)=1

MAPLE

N:= 200: # for a(1)..a(N)

V:= Vector(N): L:= <1>:

for n from 1 to N do

  L:= -n*<L, 0>  + <0, L>;

  V[n]:= max[index](L)[1]-1

od:
