The Eight Trigram justu is a taijustu that uses the Gentle Fist style, which is passed down in main branch of the Hyƫga clan. In both the original and Shippuden, Neji uses this ability multiple times through the series.
So far, we have seen 16 Palms, 32 Palms, 64 Palms, and 128 Palm (which is only seen during Neji's fight with Kidomaru.)
In that pattern, the amount of attacks are doubled for each variation. Is Eight Trigram justu limited to 128 attacks? If not, what is the highest number attacks it can go?
