i threw everything at the wall here.

hexagonal radius of 9, costs between 1 and 5 (plus free square), stumps enabled, points constrained 2 cells from each corner to have a minimum cost from center of 10 or 20, and costs of 1 and 5 respectively. there must be $1 cells with minimum costs from 1 to 10, and the total cost of a symmetrical segment must equal 150. the count of $n cells must be $1 โฅ $2 + 2 โฅ etc. this shows the minimum costs; actual costs are in increasing intensity of color.
