What is a sensible prime for hashcode calculation? http://stackoverflow.com/questions/1835976/what-is-a-sensible-prime-for-hashcode-calculation of hardware multipliers. Here you have many hashcode collisions for small values of i and j for example 0 0 and 1 31 have the.. So it seems a good idea to make the smallest hashcode collision as large as possible by choosing an appropriate prime. For 31.. best prime in this sense is 486187739 with the smallest collision being i 25486 j 67194 . Nearly as good and much easier to remember..
