<p>By replacing each of the letters in the word CARE with $1$, $2$, $9$, and $6$ respectively, we form a square number: $1296 = 36^2$. What is remarkable is that, by using the same digital substitutions, the anagram, RACE, also forms a square number: $9216 = 96^2$. We shall call CARE (and RACE) a square anagram word pair and specify further that leading zeroes are not permitted, neither may a different letter have the same digital value as another letter.</p>
<p>Using <a href="resources/0098_words.txt">words.txt</a> (right click and 'Save Link/Target As...'), a 16K text file containing nearly two-thousand common English words, find all the square anagram word pairs (a palindromic word is NOT considered to be an anagram of itself).</p>
<p>What is the largest square number formed by any member of such a pair?</p>
<p class="smaller">NOTE: All anagrams formed must be contained in the given text file.</p>
