For an affine algebra of nonexceptional type in the large rank we show the fermionic formula depends only on the attachment of the node 0 of the Dynkin diagram to the rest, and the fermionic formula of not type $A$ can be expressed as a sum of that of type $A$ with Littlewood–Richardson coefficients. Combining this result with theorems of Kirillov–Schilling–Shimozono and Lecouvey–Okado–Shimozono, we settle the $X=M$ conjecture under the large rank hypothesis.

Pour une algèbre affine de type non-exceptionnel de grand rang nous prouvons que la formule fermionique dépend seulement du voisinage du nœud 0 dans le diagramme de Dynkin, et également que la formule fermionique en type autre que $A$ peut être exprimée comme combinaison de celles de type $A$ avec des coefficients de Littlewood–Richardson. Combinant ce résultat avec des théorèmes de Kirillov–Schilling–Shimozono et de Lecouvey–Okado–Shimozono, nous résolvons la conjecture $X=M$ lorsque le rang est grand.
