Bonjour à tous.
Sur internet j'ai trouvé une macro qui marche très bien le souci que j'ai c'est que les résultats sont concaténés. Pour un problème d'espace j'aimerai les avoir directement en ligne (par exemple si j ai une combianaion AB,AC j aurai AB en A1 et AC en B1 ect...et ce pour chaque combinaison) si vous pouvez m'aider à resoudre ce problème...merci d'avance.
 
Voici la macro---------------------------------------------------------------------------------------------------------------------------------------  
'1. En A1, écrire c ou p ; (Combinaison ou Permutation)
'2. En A2, écrire la valeur de R ;
'3. Sous A2, écrire la liste des N éléments ;
'4. Sélectionner A1 et activer la procédure.
 
'Exemple:
'A1 c
'A2 3
'A3 1
'A4 2
'A5 Excel
'A6 4
'A7 *
'A8 6
'
'La procédure donne alors la liste de toutes les combinaisons
'possibles de 3 éléments choisis parmi 6.
