+Alright, let's tackle 'SUCCESS' and see just how unique it can get!
+1. Step 1: Count the Letters  
+The word 'SUCCESS' has 7 letters, but it’s no free-for-all—there are repeats!  
+- S: 3 times  
+- U: 1 time  
+- C: 2 times  
+- E: 1 time  
+Erdős would call this a combinatorial party with some guests arriving multiple times.
+2. Step 2: The Formula for Permutations with Repetition 
+When letters repeat, we divide to avoid overcounting. The magic formula is:  
+$$
+\frac{n!}{k_1! \cdot k_2! \cdot \ldots \cdot k_m!}
+$$  
+Here, (n) is the total number of letters, and (k_i) are the frequencies of each unique letter.
+3. Step 3: Plug in the Values
+Let’s compute:  
+$$
+\frac{7!}{3! \cdot 1! \cdot 2! \cdot 1!} = 420
+$$
+
+4. Step 4: Reveal the Result  
+There are **420 unique arrangements** of 'SUCCESS'. Mathematically satisfying, isn’t it? It’s as if every version of success gets its own unique permutation!`,

+- I: 4  
+- S: 4  
+- P: 2
+2. Step 2: Apply the Permutation Formula for Repetition  
+The formula for such a case is:  
+$$
+\frac{n!}{k_1! \cdot k_2! \cdot \ldots \cdot k_m!}
+$$
+3. Step 3: Plug in the Values
+Here’s where we let the math do its magic:  
+$$
+\frac{11!}{1! \cdot 4! \cdot 4! \cdot 2!}
+$$
+4. Step 4: Simplify Step-by-Step  
+Let’s break it down:

+- (4! = 24)  
+- (2! = 2)  
+#### Substituting these values:  
+$$
+\frac{39,916,800}{1 \cdot 24 \cdot 24 \cdot 2} = 34,650
+$$
+5. Step 5: The Grand Finale
