For a permutation with repetitions
(nPr) / x1!x2! where x is the number of repititions.
In this case

PLZ explain how there are 36 possible 4-letter "words" (that is, letter arrangements) with three e's and one of six other letters.

Seems like there are:
       "t"      teee   etee   eete   eeet
       "l"     . . .
       "p"   . . . 
       . . .
       "n"     neee  enee   eene   eeen

 Total 6*4=24
