In mathematics
[edit]259 is:
- a semiprime
- 63 + 62 + 6 + 1, so 259 is a repdigit in base 6 (11116)[1]
- a lucky number[2]
- Assuming A=1, B=2, C=3, D=4, etc..., all the way up to Z=26, when 259 is spelled out in word form, including the word "and", and when every single number indicating its letter position is added, the value is 259.
