# LieArt — 3 different 8 dimensional irreducible representation of $\mathrm{SO}(8)$ and their decompositions

I am using the LieArt which you can download freely online https://arxiv.org/pdf/1206.6379.pdf

There are three different 8 dimensional $$\mathrm{SO}(8)$$ irreducible representations, formally it is written as 8$$_v$$, 8$$_s$$, 8$$_c$$. See p.26 of https://arxiv.org/pdf/1206.6379.pdf

Question: What will we call out of these three different 8 dimensional $$\mathrm{SO}(8)$$ irreducible representations through Mathematica? Are they represented by these?

Irrep[SO8][IrrepPrime[8, 0]]

Irrep[SO8][IrrepPrime[8, 1]]

Irrep[SO8][IrrepPrime[8, 2]]


but they seem not work?
