If one RTX4090 card can do it in +/- 249934 days (68 years). Then eighty RTX4090 cards can do it i in less than a year.
Who taught you mathematics?
249934 days=684 years
with this math, we need +400 4090 GPU to solve the 135 in 1.7 years or something like this, and in half a year but we need to use +1000 GPU

if I'm not wrong this is a hallucination
