Commentary

Variable-anchor 29-core construction derived from the 25-block decomposition at 18125=29*25^2. Start from the maximal collection of inherited whole blocks valid at 18050, then re-anchor five copies of C1={0,1,5,6} at 730, 744, 7218, 7235, and 7965. This restores 25 complete 4-point blocks = 100 points.
