A12-140 class number of IQ(2^{1/n})


Are there statements about the class number of IQ(2^{1/n}) (beside
general theorems like the Minkowski bound)?

Using PARI, I found that it equals 1 for n <= 46.

Does someone know a n for which the class number is > 1?

It can't be known that it is always 1 since this would solve an open
question.
