Affine Subgroups of the Affine Coxeter Group with the Same Coxeter Number
… ng the same Coxeter number with the affine Coxeter groups W(An), W(Dn) and W(En) are constructed by graph folding techniques. The affine groups W(Cn) and W(Bn) are obtained from the Coxeter groups W(A2n-1) and W(D2n-2), respectively. The affine groups W(E6), W(D6) and W(E8) lead to the affine groups W(F4), W(H3) and W( …
