Ivan Neretin, Table of n, a(n) for n = 1..1000


EXAMPLE

n=23, A001222 for binomial(23,k)={0,1,2,3,4,4,5,5,6,6,6,6,6,6,6,6,5,5,4,4,3,2,1,0}, thus both maximal and central values are 6.


MATHEMATICA

Select[Range[120], Function[n, ar = PrimeOmega[#] & /@ Binomial[n, Range[0, n/2]]; Max[ar] == ar[[1]]]] (* Ivan Neretin, Sep 07 2015 *)
