235 (two hundred [and] thirty-five) is the integer following 234 and preceding 236.
Additionally, 235 is:
- a semiprime
- a heptagonal number[1]
- a centered triangular number[2]
- therefore a figurate number in two ways
- palindromic in bases 4 (32234), 7 (4547), 8 (3538), 13 (15113), and 46 (5546)
- a Harshad number in bases 6, 47, 48, 95, 116, 189 and 231
- a Smarandache–Wellin number
Also:
- There are 235 different trees with 11 unlabeled nodes.[3]
- If an equilateral triangle is subdivided into smaller equilateral triangles whose side length is 1/9 as small, the resulting "matchstick arrangement" will have exactly 235 different equilateral triangles of varying sizes in it.[4]
