Properties of the First 5000 Integers  

This is a list of numbers with fairly mundane properties, such as being a square or a prime number.

In addition, for most numbers it gives the classical sequence for which the number is generated with the lowest cost, defined as the sum of a sequence's complexity score (see here for details) and a value of N for which AN equals the number.

If this sort of thing interests you, check out my numbers and large numbers pages too.
