For instance, the first counterexample must be odd because f(2n) = n, smaller than 2n; and it must be 3 mod 4 because f 2 (4n + 1) = 3n + 1, smaller than 4n + 1. For each starting value a which is not a counterexample to the Collatz conjecture, there is a k for which such an inequality holds, so checking the Collatz conjecture for one starting ...

A projective triad δ of side m is a set of 3m - 2 points, m of which lie on each of three concurrent lines such that the point of concurrency C is in δ and the following condition is satisfied: If a point P on one of the lines and a point Q on another line are in δ, then the point of intersection of PQ with the third line is in δ.
Odd One Out is a British game show based on the American version entitled Knockout. It aired on BBC1 from 16 April 1982 to 19 April 1985 and was hosted by Paul Daniels . The show is based on a short-lived American game show produced by Ralph Edwards called Knockout , hosted by Arte Johnson .
A set of polygons in an Euler diagram This set equals the one depicted above since both have the very same elements.. In mathematics, a set is a collection of different [1] things; [2] [3] [4] these things are called elements or members of the set and are typically mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other ...
The Sylvester–Gallai theorem was posed as a problem by J. J. Sylvester (). Kelly () suggests that Sylvester may have been motivated by a related phenomenon in algebraic geometry, in which the inflection points of a cubic curve in the complex projective plane form a configuration of nine points and twelve lines (the Hesse configuration) in which each line determined by two of the points ...
The set of absolute points of each type of polarity can be described. We again restrict the discussion to the case that K is a field. [16] If K is a field whose characteristic is not two, the set of absolute points of an orthogonal polarity form a nonsingular quadric (if K is infinite, this might be empty). If the characteristic is two, the ...
The sum total of fingers displayed is either odd or even. If the result is odd, then the person who called even is the victor, and can decide the issue as they see fit. [7] [8] [9] Often, the participants continue to shoot for a best two out of three. [10] From a game-theoretic perspective, the game is equivalent to matching pennies. See that ...
