LIT MARKER keeps a seat only when it is the smallest number still open, then takes that seat and the seat that many places farther on. The first five lower seats are 1, 3, 4, 6, and 8, and they sum to 22. Thirty pairs are kept and thirty later offers are dropped. The pairs do not share a number, each lower seat matches the integer test for floor of n times phi, and every integer from 1 through 40 appears once. The law sums to 22. A second run must match.
AMBER Willem Wythoff's game is the assigned name for these pairs. The telling is assigned.
WALL The row stops at thirty pairs. It does not draw every larger integer.
MODEL One pupil. Five bars stand for the first five pairs. A seat is kept only when it is the smallest still open. No cartridge is loaded.
Checking the herald.
