- ... that the
clique problem of programming a computer to findcomplete subgraphs in anundirected graph was first studied as a way to find groups of people who all know each other insocial networks ? - ... that the
Herschel graph is the smallest possiblepolyhedral graph that does not have aHamiltonian cycle ? - ... that the
Life without Death cellular automaton , a mathematical model ofpattern formation , is a variant ofConway's Game of Life in which cells, once brought to life, never die? - ... that one can list every
positive rational number without repetition bybreadth-first traversal of theCalkin–Wilf tree ? - ... that the
Hadwiger conjecture implies that the external surface of anythree-dimensional convex body can beilluminated by only eight light sources, but the bestproven bound is that 16 lights are sufficient? - ... that an
equitable coloring of agraph , in which the numbers of vertices of each color are as nearly equal as possible, may require far more colors than agraph coloring without this constraint? - ... that no matter how
biased a coin one uses,flipping a coin to determine whether eachedge is present or absent in acountably infinite graph will always producethe same graph , theRado graph ?
