I know of nothing built in to Sage, but this is easy to write. The following
seems to work, even if it isn't very elegant:
def factrep(nn):
n=nn
i=1
while factorial(i)<=n:
i+=1
i-=1
ans=[]
while i>0:
d=n//factorial(i)
ans.append(d)
n-=d*factorial(i)
i-=1
return ans

Subject: [sage-support] Factorial Carry Value in Python
Let be s between 1 and l!-1 an integer value then s can expressed uniquely than:
s = u1*(l-1)! + u2*(l-2)!+ ... ul*0
Is there any function to find the values u1, u2, ..., ul in SAGE or python?
