Other aspects of the number 1414

According to “What’s Special About This Number?”,

1414 is the smallest number whose square contains 3 consecutive 9’s.

The square is 1,999,396. I like how the last three digits are also multiples of three.

Thanks to NumberGossip.com I find that 1414 is:

  • Even (of course)
  • Composite
  • Deficient
  • Odious
  • Square-free
  • Undulating

1414 is apparently both a triangular number and the smallest triangular number with four digits. It is also the Decimal expansion of sqrt(2) truncated and rounded to 4 places. There are many other mathematically esoteric aspects of 1414 if you care to check them out.
