Computational - pencil and paper ready. This is the value of Euler's [OY lurz] totient [TOH shent] function for 427. It's also the smallest number divisible by every number except seven from 1 through 10, and it's the positive geometric mean between 90 and 1,440. This number is the area of an isosceles right triangle inscribed in a circle of radius 6 root 10, and it's also the sum, in degrees, of the ex- terior angles of a decagon, an octagon, a heptagon, a hexagon, a pentagon, a quadrilateral or a triangle.
