Brute-force algorithms to count the number of solutions are computationally manageable for n = 8, but would be intractable for problems of n ≥ 20, as 20! = 2.433 × 10 18. If the goal is to find a single solution, one can show solutions exist for all n ≥ 4 with no search whatsoever.

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. [1] For example, the word anagram itself can be rearranged into the phrase "nag a ram"; which is an Easter egg suggestion in Google after searching for the word "anagram".
For every 3 non-theme words you find, you earn a hint. Hints show the letters of a theme word. If there is already an active hint on the board, a hint will show that word’s letter order.
All games of Anagrams are played with letter tiles. Different editions of the game use different rules, and players now often play by house rules, but most [citation needed] are variants of the rules given here, taken from Snatch-It. [4] To begin, all tiles are placed face down in a pool in the middle of the table.
The first such anagram dictionary was The Crossword Anagram Dictionary by R.J. Edwards [1] In the other kind of anagram dictionary, words are categorized into equivalence classes that consist of words with the same number of each kind of letter. Thus words will only appear when other words can be made from the same letters.
"the answer to [the ultimate question of] life the universe and everything" provides the answer "42" as a result in reference to the Douglas Adams novel series, "The Hitchhiker's Guide to the Galaxy". [21] [23] It is believed to be the first Google Easter egg, [4] predating the calculator in which it is now revealed.
These are geographic anagrams and anadromes. Anagrams are rearrangements of the letters of another name or word. Anadromes (also called reversals or ananyms) are other names or words spelled backwards. Technically, a reversal is also an anagram, but the two are derived by different methods, so they are listed separately.
