It goes even further than that. After vigintillion, you have steps of 10^30 that go trigintillion, quadragintillion, quinquagintillion, sexagintillion, septuagintillion, octogentillion, nonagentillion and centillion, with the 10^3 prefix in the front. If you really need to ramp up further, centillion can be prefixed by any of the other major prefixes, so 10^30 centillion is a decicentillion, and so on.

It’s a whole system that I had a hyperfixation on as a kid so I remember it quite well.
