Has my textbook made a mistake? (Questions about genes)

- in my book it says the genetic code is a triplet code where three nucleotide bases code for an amino acid, and then it says there are four bases pranged in groups of three?

I think what your book means by the next sentence is that the genetic code is made up of four bases. That is, with this selection of four bases, you assemble them in a specific order to make the genetic code.

Arranged in groups of three just refers to the triplet code

So the genetic code is a strand of nucleotide bases, and there are four different types (A, T/U, C and G). The genetic code is then read in groups of three bases.
Three bases will code for one amino acid.
