Summary A conjecture of Grünbaum states that everyn 3 -configuration in the real plane can also be realized in the rational plane. We prove this conjecture forn ⩽ 12 by computing rational coordinates for all 31 types of 113 -configurations and all 228 types of 123- configurations in the classification of Daublebsky.
