In Einstein gravity coupled to power Maxwell invariant [23], it is shown that for s > n/2 and s < 0, the singularity at r = 0 for the
solutions with non-negative mass is spacelike, and therefore it is unavoidable. These solutions with positive mass present black branes
with one horizon. But here, in Gauss–Bonnet gravity, we have a extra parameter, α, and one can set the parameters of the solutions to
have timelike singularity for all values of nonlinear parameter.
