That way 2/3 of the integers are eliminated from further testing.

-30 bones in each arm and leg (3 x 2 x 5)

-26 vertabrae(though 2 are composites of 5 and 4, so in all there are 33 = [2

-24 ribs( 2

-3 fused pelvic bones

These are funny facts to know, but they lack the 'therefore' part: do they influence math in general, or number theory in particular?

But even so there are an infinite number of integers divisible by 6547. And they could be put into 1-1 correspondance with numbers divisible by 2. [tex] 6547n\Longleftrightarrow2n[/tex]

Tinyboss: Primes in general are fundamental to number theory, and naturally the first primes come up more often: half of the natural numbers are even, but not nearly so many are divisible by, say, 6547.

Yeah, I was playing a little fast and loose there, but what I meant was small integers, the kind like trini mentions, for instance, or the kind that show up as the order of sporadic groups, and so forth. Not that |Z/nZ| depends on n.

The square of all primes greater than 5 is either (1 mod 30) or (19 mod 30).
