greetings seq fans.

for a couple years now i've been working on a list of the most distinctive
fact about each small positive integer.  for example, 12 is the smallest
abundant number, 52 is a bell number, 76 is automorphic, and 153 is the sum
of the cubes of its digits.  for space reasons i've only been concentrating
on numbers below 10,000.

i've considered entries from "the lure of integers", "the penquin
dictionary of curious and interesting numbers", and "the kingdom of
infinite number", as well as looked at all the "core" sequences at the EIS.
are there other sources that i have missed?

the current list can be found at:

additions, suggestions, or corrections.  thanks.
