Find this unique composite cat given the information in this title.


The answer is



$\frac{3!}{4} = \frac{6}{4} = 1 + \frac{1}{2}$ leaves a remainder

Hint from question

cat - may be four legs


2 is the only even prime number. Before 4 , 2 occurs only once and 4 is a multiple of 2. And 3! = 6 = 3.2.1 has only one 2, hence it leaves a remainder. $$$$ Whereas for other composite numbers say, $n$, $(n-1)!$ has all the factors of $n$, and thus doesn't leave a remainder.
