Philosophy I / The Atomists: Leucippus and Democritus
Practice question · Numerical answer

Democritus compares atoms to letters: a few types arranged differently give unlimited variety. If an alphabet has 24 letters, how many distinct three-letter sequences are possible, allowing repeats?

Hints
  1. Each of the three positions can independently hold any of the 24 letters.
  2. Compute 24 to the power 3.
Show the answer

13824 (answers within ±10 count)

Why

243=13,82424^3 = 13{,}824 sequences from just 24 letters in three positions. This is exactly the combinatorial point Democritus made: a small number of element types generates unlimited variety through arrangement alone.
