For character creation my group sometimes uses a weird method to generate stats. We roll 6 stat arrays using 4d6D1 (rolling 4d6 and dropping the lowest), and arrange them on top of one another to make a 6x6 matrix. We can then choose any row, column, or diagonal as our stat array.

An example of a matrix generated this way:

Giving us the following options for our stat array (Row 3 seems to be the best in this case):

LR and RL are the diagonals from the Top Left to the Bottom Right, and Top Right to the Bottom Left respectively.

###What is the average point buy of using this method? And how is it calculated in this case?
