This is a view of the 36 flagstones of Joe’s patio.
Joe has numbered them, so that starting on flagstone 1 (shown) and stepping from one flagstone (not diagonally) to an adjacent one in order, one will finish back on flagstone 1 after stepping on all the other 35. The arrows indicate in which direction to step from certain flagstones.
What are the numbers of the flagstones E, N, I, G, M and A?
