202 is a
Smith number, meaning that its
digit sum and the sum of digits of its
prime factors are equal. It is also a
strobogrammatic number, meaning that when shown on a
seven-segment display, turning the display upside-down shows the same number. There are exactly 202
partitions of 32 (a
power of two) into smaller powers of two. There are also 202 distinct (non-congruent)
polygons that can be formed by connecting all eight
vertices of a
regular octagon into a cycle, and 202 distinct (non-isomorphic)
directed graphs on four unlabeled
vertices, not having any
isolated vertices. ==See also==
