Distinct even and odd asymptotic constants over finite fields

Prove or disprove that the limiting constants \(L_e\) and \(L_o\) for normalized \(g\)-difference bases in even- and odd-dimensional vector spaces over \(\mathbb{F}_p\) are unequal, namely that \(L_e\ne L_o\).

Background

For a fixed odd prime pp and natural number gg, the paper proves that the normalized minimum sizes of gg-difference bases in Fp2k\mathbb{F}_p^{2k} and Fp2k+1\mathbb{F}_p^{2k+1} converge separately to positive limits LeL_e and LoL_o. Unlike the integer case, the authors cannot establish whether the parity-dependent limits coincide and explicitly formulate their expected inequality as a conjecture.

References

Contrary to the situation in the integers, we in fact conjecture that these limits are not the same.
