FORMULA

a(n) = a(3,n) where a(q,n) = A(q,n) / gcd(n+1, q-1) and A(q,n) is defined in A003787. - Sean A. Irvine, Sep 18 2015

MATHEMATICA

f[m_, n_] := Block[{g, x, y}, g[x_, y_] := x^(y (y + 1)/2) Product[x^k - 1, {k, 2, y + 1}]; g[m, n]/GCD[n + 1, m - 1]]; f[3, #] & /@ Range[0, 8] (* Michael De Vlieger, Sep 18 2015 *)
