Conjecture 1. Let F_n(x)=sum_{j=0..n} A187660(n,j)*x^{(n-1)*j}. Let f_n in Z[x] be any polynomial in x of degree d such that 0<=d<=(n-1)*(n-2). Then the sequence of coefficients of the series expansion of f_n(x)/F_n(x), when taken over Z/kZ, is periodic with period p <= (n-1)*A220555(n,k), for all n,k > 1. (Cf. [Coleman, et al.] which deals with for the case for n=2 (generalized case for n=2 (Fibonacci).)
Conjecture 2. If G a cyclic multiplicative group generated by an n X n integer matrix g over Z/kZ, then |G|<=T(n,r,k), for some r<=n.
Conjecture 3. If T(n,k) is optimal, then n is a Queneau number (Cf. A054639).
