... Theorem 2. The Second Principle of Mathematical Induction: A set of positive integers that has the property that for every integer k, if it contains all the integers 1 through k then it contains k + 1 and if it contains 1 then it must be the set of all positive integers. More generally, a property c ...

... triangle with area n: there are rational a, b, c > 0 such that a2 + b2 = c2 and (1/2)ab = n. In Figure 6.1, there are rational right triangles with respective areas 5, 6, and 7, so these three numbers are congruent numbers. This use of the word congruent has nothing to do (directly) with congruences ...

... regular if it is transitive and the point stabiliser H is a normal subgroup of G; such an action is isomorphic to the action of G/H on itself by right multiplication. In particular, since every subgroup of an abelian group is normal, we see that every transitive action of an abelian group is regular ...

If 2 people of different parities shake, then they both swap parities and the odd parity count is unchanged. If 2 people of the same parity sh ...
