A harmful truth is better than a useful lie.

#35 of a series that is never used. An abandoned car park. Campbell Street, Hobart, October 2010.

Who knew that number 35 was so important? Did you know that…?

  • 35 is the sum of the first five triangular numbers, making it a tetrahedral number.

  • 35 is a centered cube number, a pentagonal number and a pentatope number.

  • 35 is a highly cototient number, since there are more solutions to the equation x - φ(x) = 35 than there are for any other integers below it except 1.

  • There are 35 free hexominoes, the polyominoes made from six squares.

  • Since the greatest prime factor of 352 + 1 = 1226 is 613, which is obviously more than 35 twice, 35 is a Størmer number.

All I know is Rule 35 of the Internet!
