Great. Now, according to this list, 152 seems to be the smallest integer without an interesting property, which of course would make it interesting, which of course would make it *not* the smallest integer without an interesting property ...

[I learned about this puzzle from John P. Burgess, who starts a talk on Tarski with it (http://www.princeton.edu/~jburgess/Tarski.doc).]

how bout
the sum of all 2 digit combos -100 times 2
2*(21+12+52+51+15+25-100)

Xan someone tell me the answer to this question. Write 225 as a product of prime factors can someone give me the answer please

for 10,000 you could put
10000: The first number with 5 digits
