How many five-letter palindromes are there (using ordinary 26 letter alphabet)?
I was thinking it was either using permutation with first three leters or using 26 cubed.
Thanks

So basically you are looking for words of the form $ABCBA$, where $A,B,C$ can be one of the possible $26$ letters. Each of the $A,B,C$ has $26$ possibilities (since there is no restriction on $A,B,C$), so the total number is $26^3$.
