Probability of the Head appearing thrice consecutively is $\frac{1}{8}$.

So, if the coin is tossed $24 (3 \times 8)$ times, once the Head will appear thrice consecutively.

But then again, I'm not entirely sure about the conditions of the problem.

Maybe it's different from the way I have understood and structured the solution.

More details (if any) will be helpful.
