Via Web Curios (much more to explore on the weekly roundup), we are directed towards an list of the first ten-thousand digits as indexed by Erich Friedman with a distinguishing fact for each that makes the number special. Among the new and revisited concepts we learned about our favourites were seventeen possible wallpaper groupings that can cover a plane with an indefinitely repeating motif—patterns often found in textiles and tessellations, Mersenne Primes, the weird sequence in the eight thousand nine hundred and seventies that all equal 8 + 9⁴ + 7⁴ + n and Narcissistic Numbers, like 153 (=1³+5³+3³) which may be amusing for amateurs and in puzzles (see also) but hold no mathematical significance.
