To find the position of the word QUEEN:
\[\bullet\] The number of words starting with E is 4! = 24.
\[\bullet\] The number of words starting with N is \[{{4!} \over 2} = 12\].
\[\bullet\] The number of words starting with QE is 3! = 6.
\[\bullet\] Number of words starting with QN is \[{{3!} \over 2} = 3\].
Therefore, the position of the word QUEEN is next to the sum, 24 + 12 + 6 + 3 = 45.
That is, the word 'QUEEN' will be on 46th position.
