The number 36 is composite: 36 = 2^2 x 3^2. Long experience with division-method hashing schemes has established that the use of composite hashing moduli produces significant clustering at their prime factors. Here you may expect disproportionately high numbers of the hash values 2 and 3.
For a hashing modulus of 46 = 2 x 23 clustering instead occurs at 2 and 23. Without knowing more about the uses you plan to make of these hash values it is hard to know how serious a limitation this clustering will be, but you should be aware of it. Also worth noting is that if 37 had been chosen as the hashing modulus originally---say by treating A-Z, 0-9, and $ as licit characters---clustering would have been avoided entirely because 37 is prime. Analogously and serendipitously, if you made 47 characters licit, thus making 47 your hashing modulus, you could avoid clustering too since 47 is also prime. John Gilmore, Ashland, MA 01721 - USA
