1,2

When (as at n=105) coefficients are not equal 1 or -1 then terms in C[n,x] are counted with multiplicity.

Table of n, a(n) for n=1..59.

A070536(n)=A051664[n]-A06530[n] > 0

n=21: Cyclotomic[21,x]=1-x+x^3-x^4+x^6-x^8+x^9-x^11+x^12 has 9 terms while largest prime factor of 21 is 7; 9 > 7, 21 is here.

Tells when A070536(n)=A051664[n]-A006530[n] is not equal to 0. Cf. A006530, A051664, A070776, A070776.
